✦ Synopsis

A simple interface between a capillary supercritical fluid chromatograph and an Extranuclear Simulscan mass spectrometer is described. The SFC column is directly inserted into the ion source through the existing GC-interface. The system is equipped with a splitting device which allows simultaneous El/ MS and flame ionization detection when C 0 2 is used as the supercritical phase. The effect of source temperature and pressure on C02 clustering was studied for optimization of source conditions.The performanceof thesystem wasevaluated witha series of model compounds and standard mixtures.
