Click-On Inline Traps

The carrier gas must contain less than 1 PPM of oxygen, moisture ...

The carrier gas must contain less than 1 PPM of oxygen, moisture or other contaminants to prevent column degradation, increase lifetime and decrease stationary phase bleed. Click-On Inline traps will definitely contribute to achieve this purity and to obtain chromatographic results free of ghost peaks, allowing the analysis of trace compounds. It will improve system performance, reduce time and cost in equipment maintenance. The advantages of using gas line purifiers with Click-On connectors allow for in-line cartridge exchange without introducing oxygen. Spring-loaded check valves seal when a filter is removed and open only when a new filter has been locked in place. There is no need to loosen and tighten fittings every time a trap is changed and your system will not be contaminated in the process. Make-up gas should also be free of contaminants such as water and hydrocarbons to avoid noise in the detector. Features • High Impurity Holding Capacity. • Trap Provides 99.9999% purity Exhaust Gas. • Click-On connectors facilitate quick and safe cartridge replacement • Polymeric trap with glass interior prevents diffusion of contaminants. • Steel trap with increased retention capacity. • Trap exhausted indicator. · All materials used are recyclable or renewable. · Specific traps for helium and hydrogen available. · Each filter is managed by a unique serial number.

ECD & MS Triple filter to remove O2/Moisture/Hydrocarbons from carrier gas


GC/MS Triple filters specific for Helium from the carrier gas, removes O2/Moisture/Hydrocarbons and is conditioned with Helium.


FID High capacity filters to remove O2/moisture/hydrocarbons from the carrier gas and 2 combi filter hydrocarbons/moisture for

purifying gases (air and H2) used in a FID.


LC/MS filters to purify the N2 from hydrocarbons and one particulate air filter


TOC Filter for removal of carbon dioxide and sulphur from a gas stream is used in combination with a humidity filter


Use moisture filters :Moisture in carrier gas lines will prematurely degrade oxygen and hydrocarbon traps and increase detector noise.

As a precaution, we highly recommend installing a moisture trap before the hydrocarbon and oxygen traps on all carrier gas lines.


Use Oxigen filter: Oxygen is a column killer. It is present even in UHP gases, as minutes leaks at fittings allow oxygen to influx against

the concentration gradient. Because oxygen can enter a gas line at any fitting or during gas bottle exchange, the oxygen trap should be

the last connection before the gas line enters the chromatograph


Use Hydrocarbon filter: Use a hydrocarbon trap if your gas has a potential source of hydrocarbon contaminants or if you suspect you are

observing carrier gas ghost peaks. Install the hydrocarbon trap after the moisture trap, to prevent moisture from degrading the hydrocarbontrapping

ability of the activated carbon in the hydrocarbon trap.


Fuel Gas filter: Is a combi (hydrocarbon/moisture) filter. The Fuel Gas Filter is perfect for purifying flame ionization detector (FID) fuel gases, removing

both moisture and hydrocarbons. Using the Fuel Gas Filter for FID Hydrogen and air will produce a stable baseline, improving overall reproducibility and sensitivity.
