Due to the various health risks of different element species, there are a multitude of applications for natural water samples in this field (e.g., Cr and Sb speciation or Br and I determination). The investigation of heavy metal complexes with humic substances by isotope dilution SEC-ICP-MS has been described, for example, by McSheehy and Mester. Copper, zinc and molybdenum were found to form complexes with similar size fractions of humic substances in seepage water samples from soils. Sturgeon s group proposed the use of sohd phase microextraction (SPME)...

Prison et al. (1998) describes a method using sohd-phase microextraction of GHB in plasma and urine. This is a new approach for GHB analysis that shows promise in that it is simple, sensitive and requires only 0.5 mL of specimen. The linearity range was from 1 to 100 pg mL in plasma and from 5 to 150 pg mL in urine with a Emit of detection of 0.05 and 0.1 pg mL for plasma and urine, respectively. The limit of detection was calculated based on aqueous solutions because the blank plasma and urine specimens had endogenous GHB concentrations of 0.1-0.2 and 0.5-L5pgmL, respectively. The method required conversion of GHB to GBL with GBL-de as the internal standard and detection by headspace GC-MS with spectra from both CI and El ionization modes. Many methods are available for GHB and GBL analyses depending on the equipment and resources available to the laboratory.

Several methods for sample pre-concentration have been proposed liquid—liquid extraction (LLE), solid-phase extraction (SPE), soHd-phase microextraction (SPME), stir bar sorptive extraction (SBSE), and perva-poration (PV). 

SoHd-phase microextraction (SPME) is currently under investigation in many laboratories for its usefulness for a large variety of bioanalytical applications SPME involves extraction and pre-concentration with a fused silica fibre or tubing coated with a polymeric stationary phase. SPME can be performed in two-phase (sample-fibre coating) and three-phase (sample-headspace-fibre coating) systems [58].
