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.

In my 30 years of experience in running virtually every USEPA semivolatile method...the performance of the Agilent J&W DB-UI 8270D GC column has raised the bar for semivolatile analysis...The DB-UI 8270D has demonstrated: • Superior chromatographic resolution (PAHs specifically are phenomenal) • Superior inertness (reactivity of acid-fraction components like 4-Nitrophenol and 2,4-Dinitrophenol, which have low pKa values, is minimal) • Superior breakdown characteristics (4,4'-DDT and Endrin breakdown is well below all method requirements and in many examples <5%!) • Superior peak tailing performance of Pentachlorophenol and Benzidine (Benzidine, for example is Gaussian in peak shape) A

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.
