“…The solvent should be of low volatility to prevent evaporation, low viscosity to ensure rapid mass transfer, low polarity to ensure compatibility with the hollow fiber, and to prevent leakage into the sample. In addition, the solvent should provide high distribution constants for the target analytes [26]. Based on the above four considerations, six types of organic solvent (dodecanol, benzylalcohol, n-decanol, n-octanol, toluene and n-hexane) were investigated for use in HF-LPME.…”

“…SPME technology can be performed in two ways: (1) direct immersion of the fiber into the aqueous sample to extract analytes dispersed in aqueous solution; (2) exposure of the fiber in the sample headspace to extract volatile targets that are partitioned between gaseous and liquid phases [54]. SPME has been applied to OPPs analysis in various matrices with high efficiency and good reproducibility [55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71].…”

“…• C. Les analytes sont séparés sur colonne capillaire Ultra 2 avec programmation de température et détection par GC-MS. Le Les mêmes auteurs proposent une technique sensiblement identique pour doser le quinalphos dans le sang et l'urine par SPME en immersion directe suivie d'une analyse chromatographique par GC-MS [13].…”
