Abstract:
The study was carried in Chemistry Department of University of Sciences and Entomology Department of National Institute of Malariology - Parasitology - Entomology during the period of 2001-2002. A manual syringe for SPME was made by using a fused silica fiber from optical cable, one of the end of the fiber is passed through the hole of a needle of 5mL medical syringe and is attached to a piston in a protective holder of 1mL medical syringe, and the other end is coated by liquid phase polyacrylate (the fiber end in a 0.1g/mL solution of polyacrylate in dichloromethane). Then the liquid sample to adsort analytes during 30-45 minutes. At the end, the 2 needle is inserted into the GC/ECD injector port is desorbed the analytes on to the column
