| abstract | ABSTRACT OF THE DISCLOSURE Disclosed herein is an analytical apparatus com-prising a gas chromatograph, a mass spectrometer, and an interface connecting the two. The mass spectrometer com-prises a variable energy ion beam source, a magnetic sector of substantially fixed magnetic field for deflecting the ions in the ion beam according to their momentum, and a detector for detecting those ions within the ion beam which have been deflected by a given angle by the magnetic sector. The vari-able energy ion source comprises a repeller electrode, a first low energy alignment electrode coacting with the repeller electrode to define an ion-forming region, an inlet for introducing gas into the ion-forming region, an electron beam directed into the ion-forming region, a second high energy alignment electrode, and an entrance electrode separating the ion beam source from the magnetic sector. The repeller electrode is maintained at a constant potential relative to the first alignment electrode, the second alignment electrode is maintained at a potential more negative than but proportional to that of the first align-ment electrode, and the first alignment electrode is main-tained at a potential positive with respect to entrance electrode. By varying the potential of the first alignment electrode relative to the entrance electrode, the mass spectrum can be swept. |
