Chromatographic determination of non-ionic aliphatic surfactants of the alcohol polyethoxylate type in the environment


, : Chromatographic determination of non-ionic aliphatic surfactants of the alcohol polyethoxylate type in the environment. Journal Of Chromatography A. 733(1-2): 206

The chromatographic procedures available for the determination of alcohol polyethoxylates (AE) in environmental samples are reviewed. The proposed methods are classified according to their routine or confirmatory (i.e., structurally oriented) potential application. The routine analysis of AE is shown to depend crucially on the formation of derivatives amenable to UV-absorption or fluorescence detection in normal- or reversed-phase high-performance liquid chromatography (HPLC), or to volatile compounds suited for gas chromatography (GC) coupled to FID. The confirmatory methods are those requiring the mass spectrometric detection operating in the selected ion monitoring mode. Only HPLC-MS is currently capable of analysing unaltered AE. HPLC and GC separations are described together with the extraction/enrichment procedures used for the isolation of these compounds from aqueous and solid environmental matrices.

We have previously raised the possibility that the mutation rate resulting in rare electrophoretic variants is higher in tribal/tropical-dwelling nonindustralized societies than in civilized/temperate-dwelling/industrialized societies. Here, we re...

CHox-cad is a chicken homeobox gene whose homeodomain is homologous to the Drosophila caudal and the murine Cdx1 genes. Based on sequence analysis of a 2.5 kb CHox-cad cDNA clone, we deduced that the primary translation product consists of 248 ami...
