HPLC Separation of Sugars on Primesep S2 Column

July 14, 2011

Five sugars were separated on a Primesep S2 HILIC column with LC/MS compatible conditions. Various mobile phase produce different selectivity and separation. Method can be used as alternative to aminopropyl column. Primesep S2 column is stable and does not undergo rapid hydrolysis like aminopropyl columns.

Condition
Column Primesep S2, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer AmAc pH 5.0, Formic Acid
Flow Rate 1.0 ml/min
Detection ELSD 50C
