Abstract
Separated sample components from a liquid chromatograph and separated sample components from a gas chromatograph are selectively ionized in an LC/MC ion source and a GC/MS ion source, respectively. Ions of sample components obtained by the ionization are focussed into a source slit and the focussed ions are subjected to mass dispersion and detection.
