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.
Note: Traps are not supplied thermally conditioned. They must be conditioned prior to use, and used and analysed within 14 days of conditioning.
