GC Columns

Ontwsep® Gas Chromatography Columns

The Ontwsep® series of gas chromatography columns are manufactured through
stringent quality control of cross-linking and deactivation processes. This ensures
that the fused silica capillary wall-coated open tubular (WCOT) columns and
porous layer open tubular (PLOT) columns provided by OneTwo Chromatography
exhibit exceptional inertness toward acidic, basic, and mixed functional group
compounds. These columns feature extremely low bleed levels and outstanding
column-to-column reproducibility. A wide range of stationary phases is available
to meet diverse laboratory requirements.

The ultra-inert gas chromatography columns are designed to meet the demands
of trace analysis, including the analysis of acids, bases, and other reactive
compounds. They also contribute to maintaining an inert GC flow path, ensuring
superior sensitivity, column efficiency, and the integrity of analytical results. Even
at elevated temperatures, these columns deliver low bleed and high inertness,
making them ideal for demanding applications.

Features:

1. Comprehensive Range of Bonded Phases: A wide selection of bonded phases and specifications to meet diverse separation requirements in gas chromatography applications.
2. Compatibility with Multiple Brands: These columns can be seamlessly interchanged with columns from various brands, offering similar or even superior separation performance.
3. Low Column Bleed and Inert Surface: Featuring minimal bleed and a highly inert surface, these columns excel in improving resolution and addressing challenging application scenarios.
4. Stringent Production Quality Control: Each column undergoes rigorous quality testing to ensure consistent column-to-column reproducibility.
