Using Potassium Bromide in UV-Vis spectroscopy
Using UV/VIS spectroscopy, either an unknown substance can be identified or the concentration of a known substance determined. In both cases, accurate
analytical results depend on the use of very pure solvents for sample preparation, this is why I used my own variation of a regent called Uvasol.
Potassium bromide (KBr) is transparent from the near UV to long-wave IR wavelengths. It has no significant optical absorption lines in its high
transmission region. It has high UV transmittance and low UV absorbance.
