The pressure requirements for chemical ionization g.c./F.t.m.s. which restrict mass resolution and accuracy are overcome through use of a pulsed valve that provides momentary reagent gas pressures. For alternate electron impact (EI)/chemical ionization (c.i.) g.c./F.t.m.s., similar resolution for bo
