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.
| 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 |
| Class of Compounds |
Drug, Acid, Monocarboxylic acid, Hydrophilic, Ionizable, Hormone |
| Analyzing Compounds | Fructose, Glucose, Sucrose, Lactose, Maltose, Sorbitol, Sucrose, Alfa D-Lactose, Beta D–Lactose, Raffinose |
Application Column
Primesep S2
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.

HILIC Separation of Sugars on Obelisc N
March 3, 2010
Common sugars can be separated on an Obelisc N HILIC/cation-exchange column with LC/MS compatible mobile phase. Highly polar surface of Obelisc N column provides good retention for sorbitol, sucrose, lactose and raffinose. Other sugars can be separated using this column.
| Column | Obelisc N, 4.6×150 mm, 5 µm, 100A |
| Mobile Phase | MeCN/H2O |
| Buffer | AmFm |
| Flow Rate | 1.0 ml/min |
| Detection | ELSD |
| Class of Compounds |
Hydrophilic, Ionizable, Sugars |
| Analyzing Compounds | Sorbitol, Sucrose, Lactose, Raffinose |
Application Column
Obelisc N
SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
