Embodiment Construction

[0066] An embodiment of a gas chromatography tandem quadrupole type mass spectrometer (GC / MS / MS) having a data processing system for chromatography mass spectrometry according to the present invention will be described in detail below with reference to the drawings.

[0067] figure 1 is a schematic configuration diagram of GC / MS / MS according to this embodiment. In a gas chromatography (GC) unit 1 , a sample vaporization chamber 10 is provided at an inlet end of a column 14 heated to an appropriate temperature by a column thermostat 13 . A carrier gas is supplied to the sample vaporization chamber 10 through the carrier gas passage 12 at a predetermined flow rate, and the carrier gas is introduced into the column 14 . In this state, when a minute amount of a liquid sample is injected from the microsyringe 11 into the sample vaporization chamber 10 , the liquid sample is immediately vaporized and sent into the column 14 by the flow of the carrier gas. During passage through t...

Abstract

Provided is a system for helping an operator determine the target ion, collision energy and other analysis conditions. A chromatogram selected by an operator is displayed in a chromatogram display area of an MRM measurement parameter determination window. When the operator selects a point on this chromatogram, the name of a target compound which is registered in an event linked with a range of time including the selected point in time is displayed on a compound name display area. A plurality of mass spectra collected at that point in time are also displayed in a mass spectra display area in a vertically arranged form, using the same scale on the mass axis and the same scale on the intensity axis, with the scales of their mass axes aligned with each other in the vertical direction. The operator can then check whether the selected peak corresponds to the target compound.

Description

technical field [0001] The present invention relates to a system for processing data collected by a chromatograph mass spectrometer combined with a chromatograph, such as a gas chromatograph (GC) or a liquid chromatograph (LC), and The measurement results are shown on the display screen. Background technique [0002] As one of mass spectrometry techniques for identification, structural analysis, or quantitative determination of compounds with relatively large molecular weights, a method called MS / MS analysis (or tandem analysis) is widely used. There are various mass spectrometers with different structures designed for MS / MS analysis, among which tandem quadrupole type mass spectrometers are characterized by their relatively simple structure and easy operation and handling. [0003] In a commonly used tandem quadrupole mass spectrometer, ions from the sample components in the ion source are introduced into a first quadrupole mass filter (usually denoted as "Q1"), where In ...
