Metal Gas Chromatography Columns Allow Enhanced High Temperature Analysis

A new generation of metal gas chromatography (GC) columns permits separation of even highly active substances at higher temperatures than are possible with standard QC capillary columns.

The Thermo Fisher Scientific (Milford, MA, USA) TraceGOLD GC Metal Columns were designed for higher temperature ranges (up to 430 °C) than standard GC columns, and they can process highly active samples and analytes without incurring any damage.

The columns are made from stainless steel and are available in lengths from 6 m to 30 m with inside diameters of 0.25 mm or 0.53 mm. Thickness of the stationary phase coated on the inside of the columns ranges from 0.25 μm to 3.0 μm.

The new metal GC columns should optimize analytical workflows, particularly for petrochemical, environmental, forensic science, and food safety applications in which high sample volume or activity are common. These columns were built to withstand high levels of stress while preventing the column breakdown or column bleed that ultimately compromise the quality of separations.
