摘要：

Mass spectra of cytochrome-c, lysozyme and trypsinogen are recorded using a compact linear time-of-flight instrument with a matrix-assisted laser desorption/ionization source. Space-velocity correlation focusing is employed to reduce observed ion time-of-flight peak widths to nearly the limits established by each ion's isotope distribution. Mass resolution of up to 1700 is achieved. Evidence of metastable decay in the field-free flight region is also presented.
