Allgemeine Beschreibung
SPB®-Octyl Capillary GC Column has high resolution and it provides reliable congener separations.
Application: The low polarity of this column approaches squalane, making it substantially less polar than that of the widely used non-polar poly(dimethyl siloxane) columns. This column offers unique selectivity compared to non-polar and intermediate polarity columns, and can be used for confirmational analyses of PCB-containing samples.

Anwendung
SPB®-Octyl Capillary GC Column was used in solid-phase microextraction-capillary gas chromatography combined with microwave-induced plasma atomic-emission spectrometry (GC-MIP-AED), for speciation of selenite (SE(IV)) as it is an element which is essential at low levels and is considered at higher levels.

The use of solid-phase microextraction (SPME) with gas chromatography coupled to microwave-induced plasma atomic-emission detection (GC-MIP-AED) is described for selenite [Se(IV)] speciation. Aqueous standards were derivatised with sodium tetraethyl- or tetrapropylborate and extracted by SPME. Headspace extraction of the ethyl
