摘要：

A method of PCB determination in water based on direct supercritical fluid extraction (SFE) and off-line solventless SFE/GC coupling has been developed. High SFE recovery of the targeted compounds from water and high efficiency of their solventless transfer into GC were achieved. The method can be used for fast screening of water samples for PCBs at ultratrace levels.
