The reagent is applied to an entire application area by moving a spray spot of the reagent sprayed from the nozzle, on the sample plate from a start point to an end point.

Abstract: A signal intensity based on a total ion current signal or the like is calculated from mass spectra obtained by a normal mode of mass spectrometric analysis. When the signal intensity has exceeded an intensity threshold, the beginning time T0 of a chromatogram peak is estimated from that signal intensity as well as one or more previous signal intensities. An MS2 execution permission-beginning time Ts is calculated by adding, to the beginning time T0, a delay time Tdelay determined front a half-value width of the peak estimated according to an LC separation condition. At or after the point in time where the actual time passes Ts, a peak which satisfies a precursor-ion selection condition is selected on a mass spectrum obtained by the mass spectrometric analysis. Then, an MS2 analysis with the m/z of the selected peak as the target is immediately performed to obtain an MS2 spectrum.

Abstract: In a mass analysis data analyzing apparatus, centroid data is used as mass spectrum data to be analyzed. First, peaks on the centroid data are specified in order of intensity as a standard peak for identifying an isotopic cluster. The isotopic cluster is detected by comparing an emerging pattern of peaks near the standard peak and an emerging pattern of peaks of an expected isotopic cluster in the case where each valence is assumed. The valence of the determined isotopic cluster is set as the valence of the peaks belonging to the isotopic cluster, and the peak at the forefront of cluster is selected as a monoisotopic peak. With such a mass analysis data analyzing apparatus, it is possible to determine the valence of each peak and identify the monoisotopic peak in a mass spectrum.

Abstract: Intensity data of the signals produced by an ion detector are sequentially stored in a data processor, with each piece of intensity data being associated with time t required for each of the various ions ejected from an ion trap to fly through a time-of-flight space and reach the ion detector. The data obtained within a time range T2 corresponding to a measurement mass range are extracted as profile data. The data obtained within either a time range T1 before the arrival of an ion having the smallest m/z value or a time range T3 after the arrival of an ion having the largest m/z value are extracted as noise component data. Various kinds of noise information such as the noise level or standard deviation are calculated from the noise component data. Based on this noise information, a noise component is removed from the profile data. For every mass scan cycle, the noise component data and profile data are almost simultaneously obtained.
