InertCap; Gas Chromatography Capillary Columns

Why InertCap GC Columns

• High inertness
Our unique inner surface deactivation technology radically removes halogenated compounds, and Silanol groups, and the residual metals on the inner surface. It gives an excellent peak symmetry to highly adsorptive polar, acidic, basic, and metal coordination compounds.

• Low bleed
It is important to select a column with low bleed on GC/MS analyses in order to improve the S/N ratio and detection limit, and avoid the contamination at MS part. The level of the column bleed will affect the sensitivity of any MS. As the level of the column bleed increases, the signal and the sensitivity surely degrades. The cause of bleed is the elution of cyclo-siloxanes, m/z 207 for example from the phase. InertCap for GC/MS columns realize an extreme low bleed due to our superior polymerization technology.


• Inspection samples
InertCap columns are rigorously tested. We use a variety of easily-absorbed samples, such as alcohols, diols, phenols and primary amines at an ISO 9001 certified factory in Japan.

• Product stability
Retention factor(k) is one of the crucial factors to inspect the batch-to-batch stability of columns.
The retention factor of InertCap has been always >2.0 % on the CV value since its release and offering the stable columns for the customers.

k=(t₁-t₀)/t₀
t₁: Retention time of targeted compounds
t₀: Gases that are not retained

• Inspection report
Every InertCap column will be shipped with an individual inspection report.
