Traps / Gas Purifiers

Item Code: TRAPS

Choosing the right Gas Purifier :
There are variety of gas purifiers available. Some remove specific contaminents while others remove multiple contaminents from your gas stream. There are several factors you need to consider when selecting purifiers for your application. These include —

  1. Contaminents potentially present in your gas stream
  2. Flow required
  3. Gas purity level required after the gas passes through the purifier
  4. Pressure limitations
  5. Desired convenience when replacing the traps
  6. Space availability
Moisture, Hydrocarbon and Oxygen are the most commonly used purifiers for analytical applications. Some of the applications do require CO2 traps and some special applications may even require HCl traps.

Oxygen (Oxy) Traps
Oxygen is the most detrimental contaminent to analytical columns. It produces irreversible oxidation damageparticularly to polar stationary phases. Stainless Steel high capacity oxygen trap employs a time proven oxygenscavenging materials technology. A high surface area reduced metal is used to irreversibly bind any free oxygenpresent in the gas. It reduces Oxygen and moisture level below 1 ppm from standard 4.0 grade or higher lab gases.Oxygen traps are packed with metal catalyst. End cap is supplied with 1/8″ OD or 1/4″ OD compression fittings.
Hydrocarbon Traps
Hydrocarbon traps are packed with an activated charcoal that adsorbs any organic compound larger thanmethane. Size and molecular weight of the organic contaminents will greatly affect the capacity of traps and to asmaller degree of trap efficiency. Activated charcoal has a higher capacity for larger (>C4) hydrocarbons than forsmaller hydrocarbons. The hydrocarbon filter trap are also made in clear acrylic tube. The packing can easily bechanged periodically. End cap is supplied with 1/8″ OD or 1/4″ OD compression fittings.
Moisture Traps
Moisture trap removes moisture, CO2, oil & dust from wet carrier gas before it flows into your column. Moisturetraps are typically packed with modelcular sieves. Cleaner gas improves baseline stability for more accurateanalyses and it can also be used for purification of hydrogen in FID detector. The gas dry filter trap consist of120 CC total volume indicating silica gel and Molecular sieves 13X in a clear acrylic tube. Acrylic is used as thetubing material for its low permeability, which is superior to that of competitive polycarbonate tube. The Silicagel changes from blue to pink at 5% relative humidity to warn of leaks in the gas stream. The packing can easily bechanged periodically. End cap is supplied with 1/8″ OD or 1/4″ OD compression fittings.

Instrument Gas Purification
Clean gas is the key to longer column lifetime and less detector noise and accurate results. Oxygen and moisture can enter downstream of the carrier gas cylinder through fitting leaks or connectors that utilize rubber o-rings. Also, contamination of the tubing with solvents or lubricating oils can increase background noise and cause ghost peaks / wrong results with Instrument systems. Therefore, traps should always be used (even with ultra high purity gases) to prevent impurities from entering the Instrument system. Individual traps are designed to remove moisture, oxygen, hydrocarbons and other contaminants from the gas supply. Traps are available with either 1/8″ OD or 1/4″ OD compression fittings. Several common carrier, make-up, and detector gas purifiers are discussed in the following section.
