Derivatization reagents for GC, silylation, MSTFA Volume 1mL Due to a different selectivityThe most volatile trimethylsilyl amide available. MSTFA is a very strong TMS donor which does not cause any noticeable FID fouling even after long time measuring series. The already good solution characteristics can be improved by addition of submolar quantities of protic solvents (e. g., TFA for extremely polar compounds such as hydrochlorides) or pyridine (e. g., for carbohydrates). Advantages of MSTFA are complete reaction with high reaction rates,
