Instruments that measure ultraviolet and/or visible light absorbance of a sample; they are based on the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance of the sample. Accessories available.
KBr powder is graded solely by purity standards that are relevant to infrared spectroscopy. SpectroGrade KBr powder is all made from crystal boules that are suitable for IR spectroscopy based upon ICL’s testing standards. FTIR Grade SpectroGrade KBr powder is made from KBr crystal boules that are not quite beam splitter grade material and is defined as material that does not have any absorbance peaks in excess of 1.5%. FTIR Premium SpectroGrade is the equivalent of beam splitter grade material, and it is made from a blend of KBr crystal boules in which peaks range from 0.9% to 1.1% . XL Ultrapure SpectroGrade is a blend of material from rare boules that exhibit absorbance bands under 0.8% and the impurity range goes down to 0.2%. Molecular Weight: 119.00, Linear Formula: KBr.
