When difficult identification jobs call for supplementing electron ionization with chemical ionization, the DuPont gas chromatography mass spectrometer lets you c h a n g e m o d e s at t h e touch of a button without sensitivity loss. Time-consuming duplicate runs are eliminated by the ability to obtain fragment ion a n d / o r molecular weight information on the s a m e i n s t r u m e n t , in s o m e cases on the same GC peak. This is particularly advant a g e o u s in a n a l y z i n g m a n y compounds of biomedical and
environmental interest. Secobarbital and other barbiturates, for example, tend to fragment under electron ionization. Instant switching to CI solves the problem. The DuPont GC/MS also e n a b l e s you to select any of three reagent g a s e s instantly. The gas enters the source directly without passing through the column.
