Abstract
The most often used method to calibrate solid-phase microextraction (SPME) for measuring gas phase semi-volatile organic compound (SVOC) concentrations, i.e. splitless liquid injection, may cause large measurement uncertainty. This study aims to improve and evaluate direct syringe-fiber loading method for calibrating SPME by examining the repeatability, influence of solvent evaporation, and linearity of standard curve for several SVOCs typically found indoors. The direct loading method has been successfully validated for DEHP. Evaluation of this method for TDCPP, B[a]P and PCB-52, and application of the method for measuring DEHP concentration in air of a sealed chamber with PVC flooring will be conducted.
