Trace identification of plant substances by combining gas chromatography-mass spectrometry and direct deposition gas chromatography-Fourier transform infrared spectrometry

摘要

The advantages of combined gas chromatography-mass spectrometry and direct deposition gas chromatography-Fourier transform infrared spectrometry at the same level of sensitivity are demonstrated using an apolar capillary column. This technique was applied to allelochemicals present in minute concentrations. The identification of volatiles in green leaves and an alkaloid is described.
