SOLID-PHASE MICROEXTRACTION AND ITS UTILIZATION IN ENVIRONMENTAL-ANALYSIS

The solid-phase microextraction (SPME) is a new method for the extract ion of organic compounds from environmental samples which eliminates t he use of solvents. Stationary phases coating fused silica fibre are u sed to extract the analytes from the sample. After extraction the sorb ed substances are introduced into the GC system, where they are therma lly desorbed and analyzed. The SPME methods are classified according t o the physical-chemical principle as direct methods and headspace meth ods. The review deals mainly with the utilization of SPME for the prec oncentration of organic pollutants from environmental matrices giving 100 references.
