“…10,11 Static or dynamic headspace methods are the primary methods currently used to extract VOCs from water samples. The theory and construction of headspace methods have been reviewed by Koester and Clement, 12 Crompton, 13 Soniassy et al 14 and Poole and Schuette 15 . These techniques provide a clean matrix-free sample, and are best suited for the determination of low molecular mass, slightly water-soluble VOCs.…”

The purpose of this review is to highlight the versatility of membrane introduction mass spectrometry (MIMS) in environmental applications, summarize the measurements of environmental volatile organic compounds (VOCs) accomplished using MIMS, present developments in the detection of semi-volatile organic compounds (SVOCs) and forecast possible future directions of MIMS in environmental applications.

“…This result seems contradictory since the higher the purge gas flow through the sample, the higher should be the volatile analytes carried to the trap. Nevertheless, as mentioned in the literature (Koester and Clement, 1993), high purge gas flow or high gas volume causes more water to be dragged to the trap, thus interfering in the adsorption of analytes. Furthermore, care was taken to remain below the breakthrough volume of the trap for all the experiments.…”

Formation of trihalomethanes (THM) was monitored at the Laboratório de Camarões Marinhos (LCM) from the Universidade Federal de Santa Catarina. THM could be present because chlorinated effluents from disinfection are discharged from the different hatchery rooms. THM quantification was done through an analytical methodology using Purge&Trap coupled with a gas chromatograph equipped with an electron capture detector. Relative standard deviation (RSD), limit of detection (LOD) and limit of quantification (LOQ) for the methodology corresponded to the ranges of 8-17%; 0.01-0.03 microg L(-1) and 0.03-0.08 microg L(-1), respectively. Linear working range was of 0.1-8.0 microg L(-1) for all compounds. Enrichment and recovery method was applied to evaluate possible matrix effects and the results varied from 71.2% to 107.9%. LCM was monitored between August and December, 2004. This study showed that THM did not increase with the increase in postlarvae production and also that the aquatic life and the surrounding environment were not affected.

“…Koester and Clement [10] have published a critical review concerning the analysis of organic pollutants in drinking water. Often large-volume water samples (typically 100 ml to II) need to be extracted to recover sufficient amounts of compounds to enable their detection by established analytical procedures.…”

“…This is an important consideration where large-volume liquid samples have to be analysed, for example trace-level analysis of organic pollutants in water may involve the analysis of 500-1000 ml aqueous samples [10]. Typical SPE disc flow rates range from 20 to 50 ml/min compared with generally less than 10 ml/min for SPE cartridges.…”
