Automated Gel Permeation Chromatography Clean-up of Soil Extracts Prior to Analysis for Semivolatile Organic Compounds by GC/MS

Gel permeation chromatography (GPC) is a size-exclusion clean-up procedure that readily separates high molecular weight interferents from sample extracts. It is used extensively for numerous environmental analysis, especially for preparing sample extracts prior to semivolatile, pesticide, PCB, polyaromatic hydrocarbons (PAHs), dioxins and dibenzofuran analysis by gas chromatography (GC) or GC/MS. This application note evaluates the Gilson Automated GX-271 GPC clean-up system to perform the post-extraction clean-up of soil extracts prior to analysis for semivolatile organic compounds.
