Besides MS detection, identification of unknown peaks in GC routine analysis of environmental samples can be aided by the use of correlations between physicochemical parameters and structure of the analytes to predict the retention times. The correlation between the boiling points and the retention times of chloro- and bromo-benzenes and of some chloro- and nitro-substituted phenols was investigated for nonpolar capillary columns and allowed tentative identification of many compounds belonging to these analogous series. ... [Pg.938]

The relative retention time (relative to dy-nitronaphthalene) and mass spectrum of each standard compound were used to assign specific isomer identification to a few of the nitro-aromatics detected in the extracts. The other nitro-aromatic isomers detected were identified by appropriate mass spectra and retention times. The availability of other specific nitro-aromatic isomers may allow assignments to be made of those compounds. [Pg.199]

For the detection and identification of aliphatic and aromatic nitro compounds reduction is used (catalytic with hydrogen or with the system metal plus HCl) amines formed on reduction can be detected and identified by methods described on p. 317. [Pg.354]

LOD and LOQ were measured to assess the sensitivity of the FID, ECD and TSD detectors for GC analysis of various nitroaromatic compounds. A parallel connection of the three detectors at the end of a single narrow-bore capillary column enabled direct comparison of the chromatograms. Structural effects on the response were evaluated and detection mechanisms were discussed. Recommendations were made for identification purposes and for analysis of environmental samples of nitro- and chloro-nitro-benzenes in a wide range of concentrations451. [Pg.1126]
