Studies on combined supercritical-fluid chromatography (SFC) using a packed column, with fast-atom bombardment mass spectrometry (FAB-MS) are described. The interfacing was successfully carried out by simply coupling a frit interface between the liquid chromatograph (LC) and the mass spectrometer. The interface was equipped with a pneumatic splitter and post-column addition device delivering FAB matrix material to a release valve which maintained a constant back-pressure at the column outlet. Using a 1% glycerol solution as a matrix compound in the release valve, the SFC/FAB-MS combination operates as well as a normal LC/MS instrument. The performance was demonstrated with a mixture of α-, β- and γ-tocopherol and Triton X-100 (poly(ethylene glycol) p-isooctylphenyl ether).
