Combined Gas Chromatography-Mass Spectrometry
1979Before the advent of gas chromatography (GC) in 1952, fractional distillation was the most widely used analytical method based on volatilization of samples. Extremely refined distillation techniques had been developed, especially in the petroleum industry, but these had several important limitations. The power of separating compounds of closely similar

Combined gas chromatography— mass spectrometry
1994Abstract Gas chromatography-mass spectrometry (GC-MS) remains the most effective technique for the separation, detection, and characterization of the components of complex organic mixtures (1). GC and MS are regarded as the ‘natural combination’, compared to other combined chromatographic-mass spectrometric techniques, as both display ...
