Claim 1

IN A GAS CHROMATOGRAPH HAVING A CAPILLARY SEPARATION COLUMN FOR A CARRIER GAS CONTAINING SAMPLE COMPONENTS, A MASS SPECTROGRAPH QUANTITATIVE AND QUALITATIVE ANALYZER COMPRISING: (A) AN EVACUATED IONIZATION CHAMBER CONNECTED TO RECEIVE THE ENTIRE OUTPUT OF THE CAPILLARY SEPARATION COLUMN, SAID CHAMBER COMPRISING ELECTRON ACCELERATING MEANS, THE ENERGY OF THE ELECTRONS ACCELERATED THEREBY BEING LESS THAN THE IONIZATION POTENTIAL OF SAID CARRIER GAS BUT SUFFICIENTLY HIGH TO IONIZE SAID SAMPLE COMPONENTS; (B) TUNABLE MASS SEPARATION MEANS FOR SEPARATING BY SPECIES A FIRST PORTION OF THE IONS FROM SAID IONIZATION CHAMBER; (C) A QUALITATIVE DETECTOR ELECTRODE FOR DETECTING EACH OF SAID SPECIES; (D) A QUANTITATIVE ELECTRODE FOR RECEIVING A SECOND PORTION OF THE IONS FROM SAID IONIZATION CHAMBER BEFORE SEPARATION AND FOR DETECTING THE OVERALL QUANTITY THEREOF; AND (E) PUMP MEANS CONNECTED TO EXHAUST THE UN-IONIZED CARRIER GAS FROM SAID IONIZATION CHAMBER.
