Gas Purifiers for GC/MS and LC/MS

Super Clean Gas Filters
Cartridge systems make changing gas filters quick and easy. A base plate allows cartridges to be exchanged 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 longer a need for loosening and tightening fittings everytime a trap is changed and your system will not become contaminated during the proces.

Carrier Gas Purity
Carrier gas should contain less than 1ppm of oxygen, moisture, or other trace contaminants, to prevent column degradation, increase column lifetime, and decrease stationary phase bleed. The expense of using high-purity gases in combination with carrier gas line purifiers will be offset by longer column lifetime and less GC maintenance.

Contaminants cause ghost peaks to appear during temperature programming and degrade the validity of analytical data. Make-up gas also should be contaminant-free, or baseline fluctuations and excessive detector noise can occur; detector gases should be free of water and hydrocarbons, or excessive baseline noise can result. Gas purifiers remove these contaminants from gas sources, thereby improving system performance.

Why our Super Clean Gas filters are 'Simply the best'?

They are fully made of glass and metal: no diffusion and no micro leaks.
Quick Fit Base plate: No tools required to exchange, replacement of Filter Cartridge within seconds, without introducing contaminants into the system.
Easy to read indicators warns when a filter becomes saturated : allowing you enough time to order a replacement.
Helium and Hydrogen specific Cartridges Available: ready to use and operational within 15 minutes after installation.
Polymer shielding of glass filter: safety.
All materials used are recycable or renewable.
Every filter is managed by a unique serial number.

Super Clean Cartridge Product Range

Triple Filter Kit for MS/ECD/NPD
The Triple Filter Kit is an all in one solution ideal for purifying carrier gas. The kit includes 1 Triple (Oxygen/Moisture/Hydrocarbon) Filter cartridge and (1) 1 position base plate.

Fuel Gas Kit for FID
The Fuel Gas Kit Gas 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 reproducability and sensitivity.

Complete Filter Bundle Kit for FID
The Fuel Gas Triple Kit is perfect for purifying carrier gas and flame ionization detector (FID) fuel gases, removing oxygen, moisture and hydrocarbons from the carrier gas using the triple filter and removing both moisture and hydrocarbons from the Fuel gas using the two combi filters. Using the combi filters for FID Hydrogen and air will produce a stable baseline, improving overall reproducability and sensitivity.

Ultra Capacity Filter Bundle Kit for FID
Ultra purity combined with Ultra capacity. This kit contains (1) Ultra High Capacity Moisture filter, (1) Ultra High Capacity Oxygen Filter, (2) Ultra High Capacity Hydrocarbon Filters and (1) four position base plate.

High Flow Hydrocarbon Filter Kit
To meet the high flow needs of the LC/MS system, the hydrocarbon or moisture filled cartridges are positioned and placed in parallel. The incoming gas stream is split equally between the cartridges and the two streams are rejoined after purification but before the gas exits the base plate.

High Flow Moisture Filter Kit
High Flow moisture filters are ideal for central purifying solutions. Moisture in carrier gas lines will prematurely degrade oxygen and hydrocarbon traps and increase detector noise. As a precaution, we higly recommend installing a moisture trap before the hydrocarbon and oxygen traps on all carrier gas lines.

* All kits are available with Stainless steel or Brass fittings. Sizes available are 1/8" and 1/4"

Ultra-High Capacity Moisture Filter
Moisture in carrier gas lines will prematurely degrade oxygen and hydrocarbon traps and increase detector noise. As a precaution, we higly recommend installing a moisture trap before the hydrocarbon and oxygen traps on all carrier gas lines.

Ultra-High Capacity Oxygen 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.

Ultra-High Capacity 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 hydrocarbon-trapping ability of the activated carbon in the hydrocarbon trap.

Ultra-High Capacity Indicating Hydrocarbon Filter
The hydrocarbon trap is also available with AT indicator.

High Capacity Combi 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 reproducability and sensitivity. Ideal for use in combination with a zero air generator.

High Capacity Triple Filter
The Triple trap is ideal for purifying carrier gas. It contains oxygen, moisture and hydrocarbon scrubbers in one easy to change economical cartridge

High Capacity Triple Filter with AT Indicator
The Triple trap is also available with AT indicator for Hydrocarbon.

High Capacity Triple Filter Helium Specific
The Helium-Specific Triple trap is ideal for purifying helium in GC/MS systems. This trap is packed and purged under helium and contains oxygen, moisture and hydrocarbon scrubbers in one cartridge.

High Capacity Triple Filter Hydrogen Specific
The Hydrogen-Specific Triple trap is ideal for purifying hydrogen in GC/ MS systems. This trap is packed and purged under hydrogen and contains oxygen, moisture and hydrocarbon scrubbers in one cartridge.

Filter Bundle of 3
Replacement filter bundle (1 Triple and 2 Combi Filters) for the 3 Position Kit for FID.

Filter Bundle of 4
Replacement filter bundle (1 Moisture, 1 Oxygen and 2 Hydrocarbon Filters) for the 4 Position Kit for FID.

High Flow Hydrocarbon Filter Bundle
Replacement filter bundle for the High Flow Hydrocarbon Kit. Contains two High Flow Hydrocarbon cartridges.

High Flow Indicating Hydrocarbon Filter Bundle
Replacement filter bundle for the High Flow Indicating Hydrocarbon Kit. Contains two High Flow Indicating Hydrocarbon cartridges.

High Flow Moisture Filter Bundle

1, 2, 3 and 4 position base plates
A base plate allows cartridges to be exchanged 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 longer a need for loosening and tightening fittings everytime a trap is changed and your system will not become contaminated during the proces.

High Flow Base plate
To meet the high flow needs of the LC/MS system, the incoming gas stream is split equally between two cartridges and the two streams are rejoined after purification but before the gas exits the base plate.
