Sequential identification numbers are automatically provided and undisplayed, constant, unique numbers are assigned to each event registered in an analysis condition setting table 100. Since correspondence information between the identification numbers and the unique numbers changes due to the reassignment of identification numbers when an event is deleted from the table, event identification numbers for each compound are changed by referring to the correspondence information on a compound information table. As a result, it is possible to avoid the misalignment of event identification numbers between both tables. In addition, when an instruction is given to coordinate the time information or m/z information on both tables, the information on one table is reflected on the other table in accordance with the identification numbers. |

1. A chromatograph mass spectrometer equipped with a chromatograph part for temporally separating various constituents in a sample, a mass spectrometry part for executing mass spectrometry on the constituents separated by said chromatograph part, a data processing part for performing analytical processing on data collected by said mass spectrometry part, and a control part for operating said mass spectrometry part in a measurement mode which selectively performs mass spectrometry on ions having a specific mass-to-charge ratio over a specific time range, wherein said chromatograph mass spectrometer is provided with:
a) a display control means for simultaneously or separately displaying the following tables on the screen of a display part: a first table for analysis condition setting in which one or a plurality of events are described in a table format in units of events including one measurement time range of said measurement mode, one or a plurality of mass-to-charge ratios to be measured within said time range, and identification numbers as information; and a second table for analysis condition setting in which the retention time, the mass-to-charge ratio, and said identification number for designating the event to be used at the time of analysis are described in a table format for each compound to be analyzed by said data processing part; b) an identification number management means which produces said identification number for each event registered in said first table so as to form sequential numbers in said table and inserts the numbers into the identification number column of said first table; c) a coordination instruction means with which an analyst gives an instruction to coordinate at least either the measurement time ranges in said first table and the retention times in said second table or the mass-to-charge ratios in said first table and the mass-to-charge ratios in said second table; and d) a coordination control means which, when coordination is instructed by said coordination instruction means, coordinates the events in the first table with the compounds in the second table using said identification numbers and modifies the measurement time ranges, retention times, or mass-to-charge ratios in one table in accordance with the measurement time ranges, retention times, or mass-to-charge ratios in the other table. |
