Gas Filter Technical Specifications
| Oxygen Filter | Moisture Filter | Hydrocarbon Filter | Carrier Gas Filter | |
|---|---|---|---|---|
| Function | Removes oxygen as well as traces of sulfur and chlorine compounds from the carrier gas | Removes water, oil and other foreign material from the carrier gas | Removes organic compounds from gas streams | Single combination filter; removes water, oxygen and organic compounds |
| Indicator Color Change | From green to gray | From green to pale brown | No indicator | Oxygen: from green to gray Moisture: from green to pale brown Hydrocarbons: no indicator |
| Capacity | 150 mL oxygen | 7.2 g water | Approximately 7 g, depending on impurities | 100 mL oxygen, 1 g water, organics depending on impurities |
| Outlet Concentration at Operating Flow of 1-10 L/min | <50 ppb | <0.1 ppm | <0.1 ppm | Oxygen <50 ppb Moisture <0.1 ppm Organics <0.1 ppm |
The Trajan SGE gas filter system delivers high purity gases to your GC, ICP and MS systems, minimising column damage, maximising sensitivity, and reducing downtime, and are designed to provide fast stabilisation times to reduce gas consumption, and ultimately to provide clean gas.
Set up
The system consists of a range of connecting units (single, dual and quadruple port) and the filter.
The connecting unit is equipped with inlet and outlet connectors for the gas lines, and two needle-like valves that automatically initiates the flow of gas once attached. The connecting unit can be bench or wall-mounted and is available for 1/4" and 1/8" gas lines.
The filters consist of adsorbent, that is packed into a transparent and virtually unbreakable, heavy-walled polycarbonate housing. When installed onto the connecting unit, the needle-like valves puncture the PTFE seals and allow gas to flow through the filter.
