一般描述

Hydrocarbon traps are basically suitable in GC for carrier gas purification, as the name suggests they are primarily used for trapping hydrocarbons. Some hydrocarbon traps, like the Supelpure^® HC Hydrocarbon Trap, contain a carbon molecular sieve that also restricts the elution of moisture and oxygen. Surges of moisture and oxygen that enter the gas line during the installation of a new gas cylinder enter the Supelpure^® HC Hydrocarbon Trap and are released slowly, diluted by the clean carrier gas from the new cylinder. It particularly removes C₃ and other higher hydrocarbons.
Activated charcoal adsorbs hydrocarbons and other contaminants from carrier gases, air, and hydrogen. Operates efficiently for approximately six months when total hydrocarbons in the incoming gas average 10 ppm.

Dimensions:

• 120 cc Trap: 111/8in. (28.2 cm) long x 13/8 in. (35 mm) diameter
• 750 cc Trap: 161/2 in. (41.9 cm) long x 25/16in. (59 mm) diameter
• S-Trap: 71/2 in. (19 cm) long x 59/16 in. (14.1 cm) wide x 1/2 in. (13 mm) diameter [total bed length = 193/4 in. (50.2 cm); the extended bed length ensures prolonged contact between the gas and the adsorbent and provides greater working capacity]
