Text Box: General Separation Technologies, Inc.        (GS-Tek) 
They offer low-cost capillary columns, PLOT columns & direct equivalents to the well-known DB–range.  In fact, the 
founder of GS-Tek actually designed some of the DB/HP columns.  
GsBP™ phases are now included in the USP Chromatographic Columns Contents. This is major progress and an important 
step forward for GS-Tek.

Better Quality for Less

NEW: GsBP™ Wax-AQ GC columns

Current demanding GC and GC/MS applications have an increased focus on sensitive analysis of more challenging active analytes. We have successfully improved the inertness of the entire GC flow path by using Ultra Inert columns and Ultra Inert liners.


We present a new polyethylene glycol (PEG) GC Column GsBP-Wax-AQ 2632-3002 with improved aqueous resistance with little column performance degradation.  Low levels of Eg. free fatty acid and ethanol aqueous samples were tested in this method. Due to the chemical properties of these compounds, particularly the multiple active hydroxyl (-OH) functional groups and acid groups, their peaks often exhibit tailing when analyzed using traditional PEG stationary phase GC columns.
