## Abstract Solid Phase Micro Extraction (SPME) involves exposing a fused silica fiber coated with stationary phase to a contaminated water sample. The organic analytes become partitioned between the stationary phase and the water and when equilibrium is reached the fiber is removed from the soluti
A microfabricated device with C18-coated channels was used to demonstrate on-chip solid phase extraction. Sample solutions containing a neutral dye were enriched and eluted in less than 4 min. Distinct elution peaks with good signal-to-noise ratios were obtained even for highly dilute samples. The g
Stationary phases for solid-phase extraction (SPE) were analysed by ESCA and SIMS in combination with multivariate analysis (MVA). The SPEs were endcapped and non-endcapped octadodecyl-bonded silica spheres of various carbon loadings (CL). The SIMS survey spectra and ESCA survey, detail and valence
The method which will be described is based on a pre-concentration of chlorinated phenolic water contaminations in a solid sorbent. These compounds were eluted, derivatized, extracted, and determined by gas chromatography using a nonpolar capillary column. The determination of 29 chlorinated phenols
