Embodiment Construction

[0032] Hereinafter, a gas chromatograph mass spectrometer (GC / MS) as an example of the present invention will be described.

[0033] figure 1 It is an overall configuration diagram of the GC / MS of this example. In the gas chromatograph unit (GC) 10, a sample vaporization chamber 11 is provided at the inlet of a column 15 heated to an appropriate temperature by a column heating furnace 14, and a predetermined amount of carrier gas is supplied to the The sample vaporizes the chamber 11 and flows into the column 15 . In this state, if a small amount of liquid sample is injected into the sample vaporization chamber 11 by using the micro-syringe 12 , the liquid sample is immediately vaporized and sent to the column 15 along with the flow of the carrier gas. While passing through the column 15, each component in the carrier gas is separated with time, reaches its outlet, passes through the sample introduction tube 21 heated by the heater 22 at the interface part 20, and is introdu...

Abstract

A chromatograph mass spectroscope in which the measurement time range is adequately determined, any one of scan measurement, selective ion monitoring (SIM) measurement, and scan / SIM simultaneous measurement can be selected. When input setting of a measurement condition table is performed, a total ion chromatogram (51) obtained by performing scan measurement of a reference sample and a prepared compound table (52) are displayed on a screen of a display unit. The operator selects a compound to be subjected to scan / SIM measurement, marks a check in a check box in the compound table (52), and clicks an ''automatic creation'' button (54). A measurement time range with a predetermined time widths before and after the holding time of the selected compound is determined. Within the range, a scan / SIM simultaneous measurement in which the mass number featuring the compound is used as a measurement mass number is executed. A measurement condition table (53) at which the above procedures are conducted is automatically created and displayed.

Description

technical field [0001] The present invention relates to the gas chromatograph mass analysis device (GC / MS) or liquid chromatography mass analysis device (LC / MS) etc., the chromatograph mass analysis device that combines chromatograph and mass analyzer, more specifically, relates to utilizing Scanning determination and selected ion monitoring ( A chromatograph mass analysis device for simultaneous data collection. Background technique [0002] As a measurement method using a chromatograph mass spectrometer such as GC / MS or LC / MS, there are known a scanning measurement method and a selected ion monitoring measurement (hereinafter, abbreviated as SIM) method. In the scanning measurement method, a mass analyzer scans the mass number (m / z) of an ion to be analyzed within a predetermined mass number range to detect all ions contained in the mass number range. Therefore, it is useful especially when the mass number of the component to be analyzed is unclear, such as qualitative ...
