描述: Potassium bromide is transparent from the 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 analysed by grinding with potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an airtight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis.

描述: Perlite is a material that looks like granules or powder and is white in colour. It is a volcanic silica sand containing water that is industrially expanded by heat treatment (1200°C). It is composed of silica, alumina, iron oxide, titanium oxide, lime, magnesia, sodium oxide and potassium. It has a very high water retention capacity (4-5 times its weight) and is pH neutral (pH 7 to 7,2).
