J&W Standard Polysiloxane GC columns are available in the greatest variety of stationary phases, and are stable, robust, and versatile.

Standard Polysiloxane GC columns are the most common stationary phases. Polysiloxane gas chromatography columns are available in the greatest variety and are stable, robust, and versatile. Standard polysiloxanes are characterized by the repeating siloxane backbone, with a certain functional type and percent level of substitution of the groups that distinguish each stationary phase and its properties.

Chemistry Area Manager, Institut Català del Suro

Our new Agilent instruments have allowed us to reduce compound detection limits to a level customers want. And just as important, it has reduced analysis time. Intuvo allowed us to have very good resolution of peaks at very low concentrations. The separation is very good. Agilent instruments and columns make our work easier with simple and easy maintenance.

GC Columns for Analyzing Fats and Oils

The analysis of fats and oils is one of the most traditional and challenging applications in Gas Chromatography, and as such, there is a vast number of GC Columns designed specifically for these types of analyses. Unfortunately, choosing the right GC column for the right application is not an easy choice, and most people end up defaulting to a familiar choice that runs ‘just fine’, sacrificing efficiency and productivity in the long term.

This webinar will provide you with a guideline and tips to find out if you are using the right GC column and supplies choice for the right fat & oil application.
