一般描述
PrepSolv™ solvents are tailored to the requirements of preparative HPLC to facilitate scale-up from analytical to preparative separations. With their extremely low evaporation residue (< 1 mg/l) and low water content, they ensure optimal protection for columns.
应用
for preparative chromatography Prepsolv™
