| Abstract: | Following a review of gas chromatographic element-specific detection by microwave-induced plasma atomic emission spectrometry for the purposes of empirical-formula determination, current results for an atmospheric-pressure helium plasma are presented. Hydrocarbons and chlorinated organic compounds are used as models and compounds resulting from chlorination of fulvic acid are characterized. Accuracy and precision for carbon, hydrogen and chlorine determinations are reported. The former usually being better than ±5% and the latter in the range 1–3%. Manual and computer methods for empirical-formulae determination are presented and compared. |
