Polychlorinated biphenyls (PCBs) are a typical group of persistent organic pollutants (POPs), which have been listed under Annex A (Elimination) and Annex C (Unintentional production) of the Stockholm Convention. In this study, a gas chromatography tandem mass spectrometry method was developed and applied to analyze concentrations of 28 PCB congeners in some Vietnamese marine fish samples.

Measuring concentrations of metabolites of estradiol and progesterone in urine, instead of measuring serum concentrations, is common in research and also is used in patient care. The primary aim of this study was to demonstrate that analysis of urine samples dried on filter paper by gas chromatography with tandem mass spectrometry (GC–MS/MS) provides results similar to serum analyzed by radioimmunoassay (RIA).

Gas chromatography has been and it still is, one of the key tools in analytical techniques in many of the advanced research carried out over the globe. This technique has contributed tremendously and was once the main technique in the analysis of specific compounds like volatile compounds, certain pesticides, pharmaceuticals and petroleum products. The advance of this technique has resulted in several tandem instruments with application of other techniques to enhance the results obtained by gas chromatography.
