Description

For IR spectroscopy Uvasol™

  • Potassium bromide is transparent from near UV to long wave IR wavelengths.
  • In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analyzed by grinding with Potassium bromide powder, and pressing into disc.
  • Potassium bromide Uvasol™ is adjusted to a mean particle size of 150 μm.
  • Sufficient for preparation of perfectly good pellets without need for further pre-treatment and associated risk of contamination.
  • It also retains its powdery form over a period of years if stored in an air-tight condition.
  • Physical suitability for pelletising is checked by special application test and its chemical purity established by full spectrum FT-IR analysis.
