In this poster, the design of a new MALDI ortogonal TOF ion gate is described. The data show the clear selection of precursor ions using a short (~1inch) oa-TOF. The results were close to those predicted by SIMION. The transmission through the gate is high (~100%) and improves signal to noise of the MS/MS data. The precursor ion selection window using the small oa-gate is ~+/-3Da at m/z 1060 (~175 FWHM). This poster was presented at ASMS 2006 and at Desorption 2006.
