Application of Needle Trap Device Packed with Polydimethylsiloxane for Determination of Carbon Tetrachloride and Trichloroethylene in Air
Introduction \u0026 Objective: The use of modern microextraction techniques for determination and evaluation of pollutants is progressively increasing nowadays. Needle trap microextraction (NTME) technique has privileges compared to the other techniques for sampling occupa-tional and environmental pollutants from air. In this study the application of NTD technique packed with polydimethylsiloxane as sorbent for determination of two organohalogen com-pounds (carbon tetrachloride and trichloroethylene) was investigated.
