摘要
PROBLEM TO BE SOLVED: To provide an effective method for operating a tandem mass analyzer and a device. ;SOLUTION: A parent ion generated from a sample is caused to pass a mass filter 2, is caused to collapse into daughter ions in a collapse means 3, and the daughter ions are caused to pass a non-continuous output mass analyzer such as a flight time analyzer 16, or the like. The mass to charge ratio range of a possible parent is divided into plural smaller ranges, and the mass filter 2 is set to pass the ions in the respective smaller ranges successively. Flags are set to the respective smaller ranges producing objective daughter ions, the mass filter 2 is set to pass the respective mass to charge ratios in the flag- set ranges, and the mass to charge ratio of produced collapsed ions against the respective mass to charge ratios can be determined using the non-continuous output mass analyzer 16.;COPYRIGHT: (C)1999,JPO
