GL Sciences IntertCap GC Columns offer reliable quality, high inertness and ultra-low bleed. Inertness is among the most difficult attributes to achieve in analytical columns. GL Sciences’ proprietary inert processing technology completely eliminates residues of metal, halide and silanol which are in the column’s inner surface. Hence, it is possible to obtain excellent symmetry peaks for polar, basic, acidic compounds and metal ligands.
In GC/MS analysis, it is crucial to choose a low-bleed column that has a little baseline rise to improve the S/N ratio and detection limit and to avoid contamination of the MS detector. The increase in baseline is caused when the siloxane (Si-O) liquid phase is decomposed by high temperatures into cyclic siloxane, which can be seen in the MS spectrum as m/z 207. The InertCap columns for GC/MS analysis are based on superior stationary phase cross-linking and fused silica surface deactivation technologies and offer ultra-low bleed technologies.
