WebSince its UV cutoff is around 212 nm, it usually does not produce interference. However, it is important to use HPLC-grade THF to avoid interference from stabilizers that often are used with other solvent grades. It is also important to make sure the THF is fresh, as the formation of peroxides over time will increase the UV background. sicily stone white lappatoWebSolvent UV-Vis Cutoff Solvent UV Cutoff (nm) Acetonitrile UV 190 Pentane 190 Water 190 Hexane 195 Heptane 200 2-Propanol (IPA) 205 Methanol 205 Ethyl Alcohol 210 MTBE … sicily stone light grey mattWebUV absorbance, GC assay, water content and non-volatile residue ...
