## Abstract The use of solid phase microextraction for quantitative analysis of methadone in urine is reported. The proposed procedure allows the extraction of methadone from a urine matrix, avoiding sample handling and saving evaporation of solvents and concentration steps. A fiber coated with pol

Solid-phase microextraction SPME has been applied to the analysis of anorectic compounds from human urine. Urine samples from phendimetrazine and fenfluramine users, after the 1:1 dilution and addition of 400 ngrmL of Proadifen as an internal standard, have been directly sampled with SPME and analyz
A recently developed solvent-free sampling method, solid-phase microextraction, has been employed for sampling the cuticular hydrocarbons from three species of social wasps for GM/MS analysis. Comparison between the gas chromatograms of cuticular hydrocarbons obtained by microextraction and those of
