Why Should A Dedicated Moisture-Proof Box Be Chosen for FTIR

FTIR is an instrument that analyzes molecular structure and chemical composition by detecting the absorption/transmission characteristics of substances to infrared light.

Core purpose:

1. Qualitative analysis: Identify the functional groups and chemical bonds of the substance (such as C-H, O-H), and determine the type of the substance (such as organic, inorganic, polymer).

2. Quantitative analysis: Measure the content of each component in the mixture (such as impurity content, component proportion).

3. Application scenarios: Cover fields such as chemistry, materials, medicine, and environmental protection, for example, detecting plastic components, drug purity, food additives, or analyzing pollutant types.

Simple analogy: It’s like conducting an “infrared fingerprint” test on molecules. Each substance has a unique infrared absorption spectrum, which can quickly “match” and identify the components.

I. Specific Application Cases in Different Fields (Practical Scenarios + Detection Objectives)

1. In the field of chemistry/chemical engineering: Identify the functional groups of organic synthesis products (such as confirming the C=O bond in esters), determine if the reaction is complete; Analyze the purity of solvents (such as the moisture content in ethanol).

2. In the materials field: Identify the types of plastics/rubber (such as differentiating PE and PVC), detect the fiber composition (cotton, proportion of synthetic fibers blend); Analyze the resin type of coatings/adhesives.

3. In the pharmaceutical field: Verify the active ingredients of drugs (such as the characteristic spectrum of aspirin), detect drug impurities (for purity control); Identify the authenticity of medicinal herbs (such as the infrared fingerprint of licorice).

4. In the food field: Detect food additives (such as preservatives, pigments), analyze the degree of oil rancidity; Identify the authenticity of products like honey and milk powder (to avoid adulteration).

5. In the environmental protection field: Qualitative analysis of pollutants in wastewater/gas (such as volatile organic compounds VOCs), detection of heavy metal complexes in soil.

6. In the electronic/semiconductor field: Analyze the composition of chip packaging materials, detect residual pollutants on circuit boards (such as soldering flux).

II. Key Technical Parameters (Core Indicators + Popular Interpretation)

1. Wavenumber range: Commonly 4000 – 400 cm⁻¹ (mid-infrared region), covering the characteristic absorption peaks of the vast majority of organic/inorganic substances. The wider the range, the more types of substances can be detected.

2. Resolution: Usually 0.5 – 4 cm⁻¹. The higher the resolution, the clearer the peak shape, and it can distinguish substances with similar structures (such as isomers).

3. Signal-to-Noise Ratio (S/N): The higher the value, the cleaner the spectrum (less noise), and it is suitable for detecting low-content impurities (such as trace pollutants).

4. Scanning speed: The number of scans per unit time. The faster the speed, the higher the detection efficiency (such as rapid screening of batch samples).

5. Sample cell/attachment: Transmission cell (liquid/gas), attenuated total reflection (ATR, no pre-treatment required for solid/viscous samples), diffuse reflection (powder samples). The more attachments, the wider the applicable scenarios.

Why choose a dedicated moisture-proof box?

Due to the fact that the beam splitter, detector and sample chamber window in the core components of the Fourier infrared spectrometer are all made of potassium bromide material, as is well known, potassium bromide is the material with the best transmittance in the infrared band. However, it has a fatal drawback, which is that it is extremely prone to absorbing moisture. After absorbing moisture, the surface of the components will fog up and deliquesce. The infrared spectrometer manufacturer will set up double seals inside during the design process. However, as time goes by and with the changes in temperature and humidity throughout the seasons, the sealing strips will age and cracks that are invisible to the naked eye will appear. This leads to the components absorbing moisture and getting damaged, causing the spectrometer to be unable to function properly. See Figure 1 (Interferometer, detector, beam splitter. Once the components get wet, the surface of the components will deliquesce. This part cannot be repaired due to special processing and can only be replaced with new components, with a cost of up to 4,000 – 12,000  US dollars).

Everyone realized that it was necessary to control the environmental humidity to protect the infrared spectrometers. The first thing that came to mind was to install a dehumidifier. The dehumidifier worked immediately, and within one hour of starting up in an environment with 90% humidity, the water collection box could be filled up. Different power dehumidifier models were configured based on the size of different laboratories. Over a period of time, the dehumidifier became a standard accessory product for each infrared spectrometer manufacturer. However, as time went on, some fatal problems emerged with the dehumidifiers during use.

Firstly, most laboratories turned on the dehumidifiers during working hours in humid seasons and would pour out the water from the dehumidifier’s water collection box and continue to start up after work. But the dehumidifier would stop running when the water level was full, and it basically stopped running around 10 p.m. This was the reason why even with a dehumidifier, infrared spectrometers could still be damaged. 99% of the infrared spectrometers that got damp and damaged occurred during nights when there was no one on duty and the dehumidification equipment was not working. During university holidays and during the COVID-19 pandemic, due to no one being on duty, a large number of infrared spectrometers required warranty repairs. Some customers, in order to continuously reduce the humidity, connected the drainage pipe of the dehumidifier to the window (to avoid the dehumidifier stopping due to full water level). However, the principle of the dehumidifier is that the compressor starts, and this long-term operation not only consumes a lot of electricity but also may cause fire hazards due to aging wiring.

In response to this predicament, our company has developed an infrared spectrometer electronic moisture-proof cabinet. This product features a dedicated dehumidification device, which can effectively protect the interferometer and detector from damage caused by moisture absorption. The moisture-proof box complies with the PC/JEDECJ-STD-033B operation standard (i.e., humidity does not exceed 50RH%). The product can monitor humidity in real time and automatically activate the dehumidification function when the humidity exceeds the set value. It does not require consumables, has low energy consumption, and is currently sold throughout the country and exported to overseas countries and regions, providing protection for all global Fourier infrared spectrometer users.

Product Principle:

The moisture-proof module inside the moisture-proof box adopts the solid-state electrolytic technology of molecular layer film. It adsorbs water molecules within the space range into the module. The internal chemical molecular layer film removes the water vapor in the box through electrolytic micro-heating, without generating wave-like water, and does not require regular drainage or cleaning. The module is equipped with an intelligent sensing device. When the set humidity is exceeded, the moisture-proof box will automatically start dehumidification. This product only has dehumidification function and no humidification function. The molecular layer film is a special material composed of a combination of molecular sieves and silica gel components. This electronic moisture-proof box has extremely low power consumption. During daily use, there is no need to replace consumables. The dehumidification module has a validity period of 5-8 years (calculated based on the customer’s experimental environment).

Product features:

1. Humidity control range: 25RH% – 50RH%, front LCD screen with dual display of temperature and humidity

2. Opening/closing method: The upper cover is designed with damping hinge for opening and closing, effectively utilizing the upper space to avoid space waste and operational inconvenience caused by the double-door design

3. Wiring design: Hidden protection for the wiring and power supply lines, and an added protection board for the PCB circuit board

4. Dehumidification system: Intelligent humidity sensing module, using a microcomputer program system with a recyclable and circulating moisture-absorbing film to control humidity. When the humidity inside the chamber exceeds the set humidity level, the system will intelligently start dehumidification, without consumables

5. Operation: Even when powered off, it has a moisture absorption protection function. It can still use the chemical moisture absorption backup function to continue dehumidification. The humidity increase within 24 hours will not exceed 10%

Case: Thermo Scientific IS10 Custom Ultra-Low Humidity Cabinet

Introduction

In the highly regulated world of pharmaceutical manufacturing and drug development, analytical precision is not merely a goal—it is a compliance mandate. Recently, a leading biopharmaceutical enterprise in India successfully completed the on-site installation, rigorous calibration, and final acceptance of a specialized, custom-engineered laboratory storage solution manufactured by Hench.

This state-of-the-art deployment is specifically designed and optimized as a specialized anti-moisture cabinet for the Thermo Scientific IS10 FTIR Spectrometer and IN5 Infrared Microscope. By delivering uncompromising ultra-low humidity control alongside a bespoke physical layout, Hench has established a highly stable, secure microenvironment that guarantees the long-term operational integrity and analytical reproducibility of these high-value optical instruments.

The Silent Threat: How Ambient Humidity Degrades Advanced FTIR Spectrometry

Fourier Transform Infrared (FTIR) spectroscopy is the backbone of modern drug analysis. The combination of the Thermo Scientific Nicolet iS10 spectrometer with the Nicolet IN5 infrared microscope provides biopharmaceutical laboratories with unparalleled capabilities. This system is essential for mapping chemical compositions, verifying raw materials, testing active pharmaceutical ingredients (APIs), and detecting microscopic contaminants down to the micron level.

Despite its exceptional analytical power, this hybrid system is highly vulnerable to ambient environmental conditions, particularly moisture. High-end FTIR spectrometers and infrared microscopes are packed with delicate, moisture-sensitive elements:

• Hygroscopic Beam Splitters and Optical Windows: Many FTIR beam splitters and windows are constructed from potassium bromide (KBr) or cesium iodide (CsI). These salt crystals are highly hygroscopic; exposure to relative humidity (RH) above 30-40% can cause them to absorb moisture, leading to fogging, cloudiness, and permanent physical dissolution (deliquescence). Once compromised, these optics scatter infrared light, reduce spectral throughput, and corrupt spectral baselines.
• Delicate Infrared Detector Assemblies: Advanced detectors, such as MCT (Mercury Cadmium Telluride) detectors, must operate under optimal optical conditions. Moisture ingress can degrade electrical connections, fog the detector’s window, and introduce signal-to-noise ratio (SNR) degradation, resulting in unstable baselines and false analytical readings.
• Precision Mechanical Alignment: Moisture can lead to micro-corrosion of high-precision internal mirror mounts and automated stages, resulting in subtle optical path misalignments that are incredibly costly to diagnose and recalibrate.

For a pharmaceutical facility, these issues translate directly into interrupted research timelines, failed quality control audits, expensive replacement optics, and prolonged equipment downtime.

Engineering the Solution: The Hench Advantage in Dry Storage Technology

Recognizing these critical challenges, Hench engineered a custom microclimate cabinet that surpasses the capabilities of standard, off-the-shelf dry cabinets. This specialized cabinet acts as a fortified shield, keeping the Thermo IS10 and IN5 microscope in an optimal dry state while remaining immediately accessible to laboratory personnel.

1. Constant Ultra-Low Humidity Output (<10% RH)

Standard commercial dry boxes struggle to maintain low humidity under frequent door openings. The specialized FTIR cabinet features a high-frequency, rapid-regeneration physical desiccant system capable of pulling interior relative humidity down to under 10% RH within minutes of closing. This dry atmosphere is well below the safety threshold required to prevent KBr crystal degradation, ensuring the internal optics remain perfectly dry.

2. Bespoke Ergonomics and Space Optimization

A significant issue with placing large spectrometers into generic cabinets is awkward physical access, which can cause accidental bumps and misalignments during instrument transfers. Hench designed this cabinet specifically around the physical dimensions of the Thermo iS10 and IN5 stack. The interior layout features reinforced, vibration-damped shelving with optimized cable routing and power outlets, allowing the spectrometer and microscope to remain powered and safely stored in a clean, organized manner.

3. Air-Tight Sealing and Anti-Contamination Engineering

In addition to humidity control, the cabinet acts as an airtight clean-room enclosure. Utilizing advanced double-layer magnetic rubber seals and a robust, heavy-duty latching mechanism, it blocks the entry of ambient dust, laboratory aerosols, and volatile organic compounds (VOCs). This keeps the instrument’s external optics clean and free of particulate buildup.

Long-Term Value and Future-Proofing Lab Operations

By adopting Hench’s tailored moisture protection technology, the Indian biopharmaceutical company has resolved a major vulnerability in its analytical workflow. The laboratory can now guarantee that its core FTIR spectrometers are always stored in a validated, low-humidity environment, drastically reducing the risk of baseline drift, optical decay, and costly unscheduled maintenance.

As global pharmaceutical standards continue to demand greater data integrity and lower tolerances for instrument variation, Hench remains dedicated to developing cutting-edge environmental control solutions. From pharmaceutical labs to electronics manufacturing, Hench continues to deliver the precise, reliable equipment protection that modern science demands.

Case: Thermo Scientific IS10 Custom Ultra-Low Humidity Cabinet

Introduction

In the highly regulated world of pharmaceutical manufacturing and drug development, analytical precision is not merely a goal—it is a compliance mandate. Recently, a leading biopharmaceutical enterprise in India successfully completed the on-site installation, rigorous calibration, and final acceptance of a specialized, custom-engineered laboratory storage solution manufactured by Hench.

This state-of-the-art deployment is specifically designed and optimized as a specialized anti-moisture cabinet for the Thermo Scientific IS10 FTIR Spectrometer and IN5 Infrared Microscope. By delivering uncompromising ultra-low humidity control alongside a bespoke physical layout, Hench has established a highly stable, secure microenvironment that guarantees the long-term operational integrity and analytical reproducibility of these high-value optical instruments.

The Silent Threat: How Ambient Humidity Degrades Advanced FTIR Spectrometry

Fourier Transform Infrared (FTIR) spectroscopy is the backbone of modern drug analysis. The combination of the Thermo Scientific Nicolet iS10 spectrometer with the Nicolet IN5 infrared microscope provides biopharmaceutical laboratories with unparalleled capabilities. This system is essential for mapping chemical compositions, verifying raw materials, testing active pharmaceutical ingredients (APIs), and detecting microscopic contaminants down to the micron level.

Despite its exceptional analytical power, this hybrid system is highly vulnerable to ambient environmental conditions, particularly moisture. High-end FTIR spectrometers and infrared microscopes are packed with delicate, moisture-sensitive elements:

• Hygroscopic Beam Splitters and Optical Windows: Many FTIR beam splitters and windows are constructed from potassium bromide (KBr) or cesium iodide (CsI). These salt crystals are highly hygroscopic; exposure to relative humidity (RH) above 30-40% can cause them to absorb moisture, leading to fogging, cloudiness, and permanent physical dissolution (deliquescence). Once compromised, these optics scatter infrared light, reduce spectral throughput, and corrupt spectral baselines.
• Delicate Infrared Detector Assemblies: Advanced detectors, such as MCT (Mercury Cadmium Telluride) detectors, must operate under optimal optical conditions. Moisture ingress can degrade electrical connections, fog the detector’s window, and introduce signal-to-noise ratio (SNR) degradation, resulting in unstable baselines and false analytical readings.
• Precision Mechanical Alignment: Moisture can lead to micro-corrosion of high-precision internal mirror mounts and automated stages, resulting in subtle optical path misalignments that are incredibly costly to diagnose and recalibrate.

For a pharmaceutical facility, these issues translate directly into interrupted research timelines, failed quality control audits, expensive replacement optics, and prolonged equipment downtime.

Engineering the Solution: The Hench Advantage in Dry Storage Technology

Recognizing these critical challenges, Hench engineered a custom microclimate cabinet that surpasses the capabilities of standard, off-the-shelf dry cabinets. This specialized cabinet acts as a fortified shield, keeping the Thermo IS10 and IN5 microscope in an optimal dry state while remaining immediately accessible to laboratory personnel.

1. Constant Ultra-Low Humidity Output (<10% RH)

Standard commercial dry boxes struggle to maintain low humidity under frequent door openings. The specialized FTIR cabinet features a high-frequency, rapid-regeneration physical desiccant system capable of pulling interior relative humidity down to under 10% RH within minutes of closing. This dry atmosphere is well below the safety threshold required to prevent KBr crystal degradation, ensuring the internal optics remain perfectly dry.

2. Bespoke Ergonomics and Space Optimization

A significant issue with placing large spectrometers into generic cabinets is awkward physical access, which can cause accidental bumps and misalignments during instrument transfers. Hench designed this cabinet specifically around the physical dimensions of the Thermo iS10 and IN5 stack. The interior layout features reinforced, vibration-damped shelving with optimized cable routing and power outlets, allowing the spectrometer and microscope to remain powered and safely stored in a clean, organized manner.

3. Air-Tight Sealing and Anti-Contamination Engineering

In addition to humidity control, the cabinet acts as an airtight clean-room enclosure. Utilizing advanced double-layer magnetic rubber seals and a robust, heavy-duty latching mechanism, it blocks the entry of ambient dust, laboratory aerosols, and volatile organic compounds (VOCs). This keeps the instrument’s external optics clean and free of particulate buildup.

Long-Term Value and Future-Proofing Lab Operations

By adopting Hench’s tailored moisture protection technology, the Indian biopharmaceutical company has resolved a major vulnerability in its analytical workflow. The laboratory can now guarantee that its core FTIR spectrometers are always stored in a validated, low-humidity environment, drastically reducing the risk of baseline drift, optical decay, and costly unscheduled maintenance.

As global pharmaceutical standards continue to demand greater data integrity and lower tolerances for instrument variation, Hench remains dedicated to developing cutting-edge environmental control solutions. From pharmaceutical labs to electronics manufacturing, Hench continues to deliver the precise, reliable equipment protection that modern science demands.
