GL Sciences equivalent for Restek GC Columns
High Inertness
GL Sciences᾽ proprietary inert processing technology completely eliminates residues of metal, halide, and silanol which are in the column's inner surface. It is possible to obtain excellent symmetry peaks for polar, basic, acidic compounds and metal ligands.
Ultra Low Bleed
Based on superior technologies for cross-linking of stationary phases and surface deactivation of fused silica, InertCap GC columns for GC/MS analysis offers technologies with ultra-low bleed.
Quality
InertCap Capillary GC columns are manufactured and shipped under strict quality control at the GL Science factory, Japan, in accordance with ISO9001 quality certification. InertCap is tested by standard samples which include high adsorption compounds.
