US EPA Method 8270 (PAH only): GC Analysis of PAHs on SLB®-5ms

GC Analysis of PAHs on SLB®-5ms

Residual Analysis Optimized for Static Headspace GC Applications

Static headspace GC (GC-SH) is a technique used to concentrate volatile analytes prior to analysis. It can improve detection of low level volatile analytes and minimizes matrix interference by eliminating the need to inject the sample directly.

Selecting a GC Column for Specific Methods

We offer the Supelco portfolio of analytical GC columns, providing you the accuracy, precision and consistency you need.
