Potassium Bromide Pure Crystalline for spectroscopy KBr-S
Potassium Bromide Pure Crystalline Feature
Potassium bromide (KBr) is a key material used in analytical chemistry for infrared spectroscopy, particularly in the mid-infrared region (4000–400 cm⁻¹). This compound is valued for its excellent transparency and stability, making it ideal for precise laboratory measurements.
1. Spectroscopic Characteristics
-
Non-absorptive in the mid-infrared range: Potassium bromide does not absorb in this region, ensuring no interference with the sample signal during spectral analysis.
-
High optical clarity: Offers exceptional transmission performance for accurate and repeatable results in ir sample preparation.
2. Handling and Precautions
To ensure accurate measurements using potassium bromide, several precautions should be observed:
-
Purity: The compound must reach spectral-grade purity to guarantee precision.
-
Dryness: KBr must be completely dry—store it in a desiccator and replace desiccants regularly.
-
Avoid moisture absorption: During tablet preparation under an infrared lamp, avoid exposing the sample to humidity.
3. Product Performance and Applications
-
High transmittance and broad transmission band: The potassium bromide crystals and windows manufactured by Hench achieve 99.99% purity.
-
Wide applications: Commonly used in Fourier Transform Infrared Spectrometers, infrared spectrophotometers, and optical components such as beam splitters, transmission windows, and lenses.
-
Complementary tools: Often paired with high-quality Onyx mortar for sample grinding and preparation.
