InertCap®

InertCap Features

1. High Inertness

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.

 

2. 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 Series

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 include 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.
