GL Sciences is a well-known & major manufacturer of GC & GC/MS capillary columns since years.
They are producing High Inertness & Ultra-low Bleed capillary columns under InertCap brand name
They evolve continuously based on their accumulated know-how, which enables us to provide better HPLC columns for our customers.
Inertness
is one of the most difficult attributes to achieve in an analytical column. 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
In GC/MS analysis, it is important to select a low bleed column that has little baseline rise to improve the S/N ratio and detection limit, also to prevent contamination in the MS detector.
The increased baseline is caused when the siloxane (Si-O) liquid phase is decomposed by high temperature into cyclic siloxane; which can be seen in the MS spectrum as m/z 207.
Based on superior technologies for cross-linking of stationary phases and surface deactivation of fused silica InertCap columns for GC/MS analysis offers technologies, with ultra-low bleed.
Quality Assurance
InertCap Capillary 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 are includes high adsorption compounds..
Inspection Report
To achieve the highest quality assurance standards, all columns are tested for quality. The inspection report includes theoretical plate number (N) and coating efficiency (CE), to ensure optimal separation and stable quality. Also, to guarantee the specific performance of some products, a test chromatogram reporting the separation and adsorption of related standard components is included.
