What is the UV cutoff value for ethyl acetate? - WKB108122

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. WebDichloromethane (Methylene Chloride) While more stable than chloroform, dichloromethane will also degrade with time and requires a stabilizer. Alkanes such as cyclohexane, cyclohexene or amylene are typically employed as preservatives and are usually present at levels on the order of 100 ppm. bitflix.io
