Quantitative FTIR Analysis: Laboratory Applications of the Beer–Lambert Law
読む もっと読むFourier Transform Infrared Spectroscopy (FTIR) is widely used in modern laboratory analysis due to its rapidity, non-destructiveness, and ability to handle multiple sample phases. Quantitative FTIR, based on the Beer–Lambert Law, enables precise determination of component concentrations in solid, liquid, and gaseous samples. This technique is commonly applied in organic chemistry, materials science, pharmaceuticals, food quality control, and environmental monitoring. This article provides a systematic overview of the principles, methods, applications, and key operational considerations for quantitative FTIR, offering practical guidance for standardized laboratory procedures. I. Core Principles of the Beer–Lambert Law in FTIR The Beer–Lambert Law establishes a linear relationship between light absorption, sample concentration, and optical path length, […]

FTIR in Plastics and Polymer Identification: Key Applications and Advantages
読む もっと読むFTIR Accessories (Fourier Transform Infrared Spectroscopy) has become an essential analytical tool for identifying plastics and polymers. The principle of FTIR relies on the characteristic absorption of infrared light by different functional groups in polymer molecules. By comparing the sample spectrum to a spectral database, FTIR enables rapid qualitative, quantitative, and structural analysis. Its applications span research and development, production quality control, compliance testing, and recycling processes. Quick Identification of Raw Materials and Authenticity Verification Plastics come in various types, including PE, PP, PVC, ABS, PET, and PC, each with unique molecular structures and corresponding infrared absorption peaks. For example: FTIR allows manufacturers to quickly confirm whether incoming raw materials […]

Background Interference in FTIR Analysis: Sources and Effective Elimination Methods
読む もっと読むIn FTIR Accessories, background interference has a direct impact on baseline flatness, peak shape accuracy, and the reliability of both qualitative and quantitative analysis. Uncontrolled interference can obscure weak absorption bands, distort spectral features, and compromise reproducibility, particularly in trace or high-precision measurements. To support routine laboratory operation and troubleshooting, the most common sources of background interference and their corresponding mitigation strategies are summarized below. Table 1. Common FTIR Background Interference and Practical Countermeasures Interference Category Typical Spectral Features Primary Cause Recommended Action Atmospheric H₂O Broad band near 3400 cm⁻¹; peak at 1640 cm⁻¹ High ambient humidity Background scan synchronization; dry gas purging; humidity control Atmospheric CO₂ Peaks at 2360, […]
