Abstract

A simple method for interfacing capillary supercritical fluid chromatography with a commercial quadrupole mass spectrometer (SFC/MS) has been developed that yields good chromatographic peak shapes and good sensitivity. No modification of the mass spectrometer is required, and a single instrument can be used for both SFC/MS and GC/MS with conversion between modes requiring less than 20 min. SFC/MS separations and chemical ionization mass spectra of wax components, a triazine pesticide metabolite, abietic acid, and high molecular weight polycyclic aromatic hydrocarbons are reported.
