Owing to the short path length, the sensitivity of photometric detection in CE is limited. For this reason, procedures are necessary to enhance the sensitivity. This can be achieved by sample pre-concentration, improvement of the optical design and/or alternative capillary geometries [66]. Sample pre-concentration can be done off- or on-column. The off-column procedures are well described in the literature and have been applied extensively in chromatography [67]. The on-column procedures are more specific to CE and are therefore briefly discussed. [Pg.605]

Muller [76] has described a gas chromatographic method for the determination of tributyltin compounds in sediments. The tributyltin compounds are first converted to tributylmethyltin by reaction with ethyl magnesium bromide, and then analysed using capillary gas chromatography with flame photometric detection and gas chromatography-mass spectrometry. Tributyltin was found in samples of sediment and these results demonstrated that the technique has detection limits of less than 0.5pg L 1. [Pg.416]

Ion chromatography can be used to measure ionic concentrations in solution. It requires a fairly large amount of solvent and usually a suppressor column to neutralize the acidity prior to detection by conductivity. For analytical purposes, most analyses previously performed by ion chromatography are now performed using capillary electrophoresis. However, Katagi et al. used ion chromatography with indirect photometric detection to analyze for nerve agents and hydrolysis products in human serum (8). [Pg.78]
