Gas purifiers
Markes International’s specialists strongly recommend these carrier gas purifiers to avoid contamination of the analytical system with hydrocarbons, oxygen or water. General-purpose purifiers are available for standard TD–GC operation, as well as high-capacity purifiers for specialised applications.

Hydrocarbon trap
The hydrocarbon trap is ideal for the removal of C3+hydrocarbons in helium, hydrogen, nitrogen, argon–methane and air. Refill kits are also available. The trap has a maximum flow capacity of 2 L/min and the stated life is 16 cylinders.1

Water vapour trap
This molecular sieve trap efficiently removes water from helium, hydrogen, nitrogen, air, etc. The trap has a maximum flow capacity of 2 L/min and the stated life is 68 cylinders.1

Oxygen/water trap
This trap reduces O2 levels to less than 2 ppb.2 It can extract contaminating oxygen at 10 ppm from at least three 8.5 m3 cylinders, and the maximum flow capacity is 250 mL/min.

Helium purifier
This purifier removes O2, H2O, hydrocarbons, CO2 and CO from helium, giving an output gas that is 99.99999% pure.The maximum flow capacity is 8 L/min, and the stated life is 13 standard cylinders2 of 99.999% helium.

High-capacity gas purifier
This specialised gas purifier removes both O2 and H2O from any common carrier gas (except hydrogen) by a catalytic reaction. It can purify up to 60 tanks of heavily contaminated gas containing 100 ppm O2 and/or H2O at flow rates of up to 1.1 L/min. A pressure gauge should be fitted at the outlet to monitor the pressure drop across the purifier – when the drop exceeds 10 psi the purifier tube should be replaced.
