GAS PURIFICATION ESSENTIALS
Gas Traps
Capillary-Grade Hydrocarbon Trap
• Packed with an extremely high surface area, baked coconut
shell-based activated carbon.
• Purged with ultra-high purity helium.
• Reduces organics to 0.1 ppm (assuming 100 ppm input).
• Maximum operating pressure: 250 psi (1,724 kPa).
Dimensions: 11" x 1

Refillable Hydrocarbon Trap
• Removes trace impurities from carrier gas.
• Reduces organics to 0.1 ppm (assuming 100 ppm input).
• 60 µm frit prevents gas contamination by purifier particles.
• Good for purge & trap systems.
• Refillable and rechargeable.
• Maximum operating pressure: 125 psig (862 kPa).
• Maximum flow: 5 L/min.

other contaminants.
• Reduces organics to 0.1 ppm
(assuming 100 ppm input).
• Each individually activated to
ensure maximum efficiency.
• Fits in GC oven for easy thermal
recharging.

Indicating Hydrocarbon Trap for Air Compressors
• Pass compressed air from an oil-filled air compressor through
this trap, to remove oil vapors and mist.
• Indicator changes from pale pink to deep pink.

High-Capacity Split Vent Trap
• Reduces the release of hazardous materials from the capillary
split vent into the lab.
• Includes connecting lines and mounting kit.
Dimensions: 6" x 1" (15.2 x 2.5 cm)
ECDVent Trap
• Reduces the release of hazardous materials from the ECD
vent into the lab.
• Includes connecting lines and mounting kit.
Dimensions: 6" x 1" (15.2 x 2.5 cm)
Carrier Gas Purity
Carrier gas should contain less than 1 ppm 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.
