GAS PURIFIERS - FROM CRS
CARRIER GAS CONTAMINANTS CAN LEAD TO GC COLUMN DEGRADATION, CAUSING INTERFERENCE WITH YOUR CHROMATOGRAPHY SUCH AS DECREASED SENSITIVITY AND INCREASED BASELINE NOISE
The Advanced Filter System (AFS) removes impurities such as oxygen, water and hydrocarbons from inert gases and hydrogen to low ppb levels. Proper installation of the AFS reduces impurities, increases sensitivity levels and improves performance.
The two part system includes a small stainless steel manifold and a high capacity filter cartridge. It can be attached to a laboratory wall or bench with brackets included. Each connection in the AFS is made with two fluoro-elastomer seals. The polycarbonate shield that surrounds the glass indicator section of the filter is sealed, so the gas flow is secure even if the glass is broken.

This is an improved, compact indicating filter for high-efficiency oxygen removal, suitable for use with chromatography carrier gas streams. It removes oxygen to low-ppb levels, with an indicator that changes color from green to gray when adsorption capacity is depleted.

We recommend using the Indicating Oxygen Trap (at top) downstream from this Model 1000 trap to show when its capacity is depleted.
This is an advanced-design gas filter for applications requiring high-efficiency moisture removal with the benefit of a depletion indicator. Up to 6 grams water is removed to low-ppb levels. The adsorbing materials are Molecular Sieve 5A and cobalt-free CoFree(TM) indicator, held in a sturdy glass tube. The gas to be purified contacts only glass, metal and the adsorbents.

The Model 300 Hydrocarbon Trap removes hydrocarbons from hydrogen and other gases. It contains 500cc's of pure activated charcoal - more than twice the capacity of other leading hydrocarbon filters -removing all hydrocarbons except methane at room temperature. The all-metal cylinder rated to 1000psig.

During split injection mode, more than 99% of your sample is vented to the atmosphere. The Split Vent Trap contains 1200 milligrams of pure activated charcoal which captures these volatile contaminants venting from split/splitless injectors. The Split Vent Trap consists of the inner glass adsorbent tube with nickel plated end fittings, clear plastic protective outer sleeve and 1/8" tube fittings. Each trap comes with three replacement tubes.
