Abstract
The peak shape narrows and the resolution improves if the ions are simply r
eflected back and forth through a conventional quadrupole mass analyzer, CO
+ and N-2(+) at m/z = 28 are separated to 50% valley with half of the origi
nal signal remaining. These two ions can be resolved to baseline (m/Delta m
) = 5000 with 1% of the original signal remaining.
