Abstract
The gated trapping, RF-only mode and frequency focusing were investigated for in-field MALDI FTMS. It was observed that gated trapping with high voltage pulses can stop within the FTMS trap in-field MALDI generated ions, which have wide ranges of mass and velocity. It was shown that substantial detection performance improvement in-field LD and MALDI might be achieved with trap frequency focusing and a high voltage RF-only mode event. Additions were made to the existing configuration of a 3-tesla Finnigan T30 FT/MS mass spectrometer including a radio coil and a switch array that intercepts the analog drives normally connected to the trapping plates.
