Abstract:
An method for sample preparation using solid phase extraction. Using an apparatus comprising a SPE cartridge and a sorbent-containing gas filter which contains a sorbent and is detachably connected to the SPE cartridge the gas used to dry the SPE cartridge is purified by passage through the gas filter, thereby preventing contamination of the SPE sorbent by airborne contaminants.
