The time-of-flight effect in Fourier transform mass spectrometry (FTMS) with an external ion source was quantified. The time-of-flight profiles of ions of different masses were measured by stepping the time interval between the ionization pulse and the gating of the trapping voltage (T gate ). The o

## Abstract The determination of the mass discrimination effect of matrixβassisted laser desorption ionization mass spectrometry (MALDI MS) over a wide __m__/__z__ range was made by determining the relative amounts of prepurified protein monomer and dimer species present in reconstituted mixtures.
Simple circuitry was developed for detector bias grating as an effective and convenient scheme for conserving the charge in detectors used in mass-analysed laser desorption/ionization time-of-flight mass spectrometry. An enhanced detector response by a factor of 3-10 was observed by detector gating
Oligonucleotide sequencing by fragmentation in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry has been demonstrated. With this sequencing method, the preparation of oligonucleotide ladder products and gel electrophoresis are not required, thus the sequencing
