Alltech Gas Purifiers- Hydrocarbon, C02, and Sulpher Traps

Hydrocarbon, C02, and Sulfur Specifications

*Efficiency applies to compounds >C4.

Alltech Hydrocarbon Traps Eliminate Detector Noise and Baseline Stability 

*Filled with a High Surface Area Activated Carbon for Maximum Adsorption.

Alltech Hydrocarbon Traps adsorb trace amounts of hydrocarbons and organics from your gas stream. Hydrocarbons and organics can cause "noisy" baselines, "spiking", and extraneous peakswhich adversely effect the performance of component-specific detectors such as the ECD or FID. In extreme cases, they can also contaminate your analytical column. Installing a Hydrocarbon Trap will eliminate contamination caused by gas streams suppliedby generators that use a compressed air source to produce gas, lower grade cylinder gases, and improperly cleaned gas lines.   Hydrocarbon traps are usually packed with an activated charcoal which will adsorb any organic compound larger than methane. Size and molecular weight of the organic contiminants will greatly affect the capacity of the trap, and to a smaller degree, efficiency. Activated charcoal has a higher capacity for larger (>C4) components than for smaller components.

High Pressure C02 Adsorber   

*Protects Molecular Sieve Columns from C02 Contamination

Alltech's High pressure C02 Adsorber removes C02 and N02 from gas streams. The adsorbent bed has the capacity to remove 25-30gmsof C02 before it is saturated and requires replacing or refilling. Water is a by-product of C02 adsorbtion and a moisture trapshould be installed downstream of the C02 Adsorber before the instrument.

Alltech Sulfur Purifier   

*Purifies Compressed Air Supply to Zero Air Gas Generators

The Alltech Sulfur Purifier removes sulfur containing compounds,C2 and greater hydrocarbons and halocarbons from almost any gas stream. The adsorbent bed of the gas purifier incorporates three separate adsorbtion chemistries to ensure optimal capacity and a high level of efficiency. It removes sulfur compounds and sulfur containing hydrocarbons from a gas stream containing 100ppm levels of contaminants to less than 10ppb. It is not recommended for use in a pure oxygen stream for safety reasons.
