Due to its excellent separation capacity and its high sensitivity gas chromatography is a widely used technique for analytical purposes. In order to get proper identification and quantification results of the analysed compounds, reference standards are needed. These PESTINORM® reference substances can be used for the characterisation of GC column properties. In addition they may also be used for the identification of unknown compounds in a gas chromatogram or as standards in quantitative GC analysis.

Vespel/graphite GC ferrules are made from quality polyimide/graphite blend. They seal with minimal torque and can be reused and repositioned along capillary columns if not over compressed in the fitting. Due to slight shrinking at high temperatures, they must be retightened after initial temperature cycles to avoid leaks.

Application: SILREST (10-50 μL) is directly injected into GC at 150-250 °C of the column temperature. The baseline of the recorder normally stabilizes within several minutes. If not, injection of SILREST is repeated until the baseline stabilizes. Note: SILREST cannot be used for glycerin, polyethylene glycol, other liquid phases having activated hydrogen such as hydroxyl group, thiol group, carboxyl group, amino group, imino group.
