Features of InertCap
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.
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.
InertCap columns are rigorously tested. We used a variety of easily-absorbed samples, such as alcohols, diols,
phenols, and primary amines at an ISO9001 certified factory in Japan.
Retention coefficient (k’) is one of the crucial factors to inspect the batch-to-batch stability of
columns. The retention coefficient of InertCap has been always >2.0% on the CV value since its
release and offering the stable columns for the customers.
Every InertCap column will be shipped with an individual inspection report.
