Gas Traps
Hydrocarbon S-Trap
• Removes hydrocarbons and
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.
• Maximum operating pressure:
60 psi (414 kPa). Dimensions:
6 3/4" x 5 5/8" (17.1 x 14.3 cm)

tech tip
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.
