Gas chromatography-flame photometric

Each sample was fortified with chlorpyrifos, as a reference standard, to determine the recovery during each extraction. Three portions of solvent were used, and the combined extract for each sample was dried with sodium sulfate. Analyses employed gas chromatography/flame photometric detection. Limits of detection for vegetation and animal tissues were 0.2 and 0.007 pg respectively. Recoveries from fortified samples were 82%. Diazoxon occurrence was infrequenf and at trace concentrations. [Pg.949]

Matthias et al. [216] have described a comprehensive method for the determination of aquatic butyltin and butylmethyltin species at ultratrace levels using simultaneous sodium borohydride hydridisation, extraction with gas chromatography-flame photometric detection and gas chromatography-mass spectrometric detection. The detection limits for a lOOmL sample were 7ng L 1 of tin for tetrabutyltin and tributyltin, 3ng L 1 of tin for dibutyltin and 22ng L 1 tin for monobutyltin. For 800mL samples detection limits were l-2ng L 1 tin for tri- and tetrabutyltin and below lng L 1 tin for dibutyltin. The technique was applied to the detection of biodegradation products of tributyltin in non saline waters. [Pg.431]

It was necessary to develop three different portable modules to achieve on-site field analysis capability. The first module consisted of pre-cleaned and sealed sample collection equipment, providing the capability to obtain any type of sample. The second module allowed for complete chemical work-up of the collected samples to prepare them for instrumental analysis. A third module contained analytical instrumentation necessary for chemical identification. The instrumentation included a gas chromatography-flame photometric detection (GC/FPD) to prescreen samples for phosphorus- and/or sulfur-bonded organic compounds. In addition, a gas chromatograph-mass spectrometer (GC/MS) was employed for positive compound identification. [Pg.65]
