Third Generation 1MHz, 2.5KV RF Source Complete:
Polarity completed its third generation 1MHz, 2.5KV RF source that integrates with TOF Mass Spec systems. The rack mount RF Source has a built in crowbar system that is connected electrically across the RF output. It is used to clamp the RF output to less 30V in less than 500ns. Crowbar triggering can be accomplished before the output extraction pulse so that system propagation delay can be accounted for to successfully detect and analyze negative ions. This will enable the BIOresearch firms to look at different proteins with TOF Mass Spec technology.
