Screening Tubes
These contain multiple beds of different types of sorbents to efficiently trap various classes of compounds simultaneously. All collected compounds are thermally desorbed and analysed by GC. These tubes are ideal for hazardous waste, indoor air quality, odours and hazardous material applications, including EPA Method IP-1B and NIOSH Method 2549.

Traps for Volatile Organic Sampling Trains (VOSTs)
These are specified by the US EPA Method 0031 in SW-846 for sampling VOCs in gaseous effluent from stationary emission sources such as hazardous waste incinerators. SKC VOST traps meet method specifications, are tested for background and pressure drop, and feature Swagelok fittings and PTFE ferrules. Traps are not supplied thermally conditioned. They must be conditioned prior to use, and used and analysed within 14 days of conditioning.
