Essential Consumables for Your GC Analysis

Gas purifiers are an essential part of your GC analysis as contaminants in gases can significantly impact on the quality of results.  Oxygen, hydrocarbons and moisture can lead to problems such as noisy baselines, moisture entering the GC column, excessive bleed and septa degradation.  Even if a carrier gas is of the highest quality, contaminants can be picked up from every part of the gas line.  Therefore. A gas purifier is needed to ensure that maximum productivity is achieved.

Cartridge Type Gas Purifiers

Trajan Cartridge Purifiers from Greyhound Chromatography make changing your gas filter simplicity itself.  The gas purifier system consists of two key parts: the base connecting unit (base plate) and the filters.  The base plate has inlet and outlet connectors for the gas lines, and the system can be wall-mounted or fixed to a bench.  Base plates come with a 1,2 or 4 filter capacity and are available for 1/4” or 1/8” gas lines.

The base plate enables the cartridge to be swopped without allowing oxygen to enter the system.  Spring-loaded check valves automatically seal tight when the exhausted filter is removed and open again when the new filter is locked into position.  No tools are required to secure the fittings, simply turn the locking collar to secure the filter in place and continue with your analysis.

Each gas filter consists of adsorbent packed into transparent and virtually unbreakable, heavy-walled polycarbonate housing, with a maximum working pressure of 15 bar (219 PSI).

Trajan Cartridge Type Gas Purifiers are designed to provide fast stabilization times to reduce gas consumption, and provide clean gas to GC and GCMS systems.

The design of the Trajan Cartridge Gas Purifiers and base plates means they can directly replace alternative brands of cartridge gas purifiers supplied by Agilent, SGT, Supelco and Restek.
