Abstract
The synchronous passer system of a JEOL spark source mass spectrometer was modified so that the ion beam could be deflected at a variable time after the start of the first of a series of discharges. The transmitted part of the ion beam was analyzed by photoplate detection.
Time-resolved measurements revealed a different behaviour between different ionic species of the same m/z value. The singly-charged atomic ions were delayed by (150±100) ns with respect to the multiply-charged ions. Molecular ions were found to be delayed by about 700 ns (Cn+) or even one or more μs (Sn+, SCn+) relative to multiply-charged ions.
The duration of the production/extraction process of multiply- and singly-charged ions was well defined in time, while this process could last for several μs in the case of polyatomic ions.
