Product Overview
Potassium bromide (KBr) IR grade is a high-purity crystalline powder specifically formulated for infrared spectroscopy applications. This grade ensures ultra-low moisture content (typically <0.05%) to prevent interference in spectral analysis, offering exceptional transparency across the infrared region (4000–400 cm⁻¹). The material undergoes rigorous purification processes to eliminate impurities like heavy metals, sulfates, and chlorides, which could otherwise distort spectral readings. Its fine particle size distribution enables uniform pellet formation when pressed with sample materials, ensuring consistent and reproducible results. The IR-grade KBr is chemically inert, making it ideal for preparing sample pellets or mulls without reacting with the analyte. Its hygroscopic nature necessitates proper storage in airtight containers to maintain optical clarity. This product is widely used in research and analytical labs where precision in infrared spectral analysis is critical, providing a reliable baseline for accurate molecular characterization.
FAQs
