Title:

SAMPLE ANALYSIS DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/198207

Kind Code:

A1

Abstract:

In the present invention, response factors that are the signal intensity ratios of various compounds to a reference compound are stored beforehand in a response factor storage unit (22). When an operator instructs that an analysis limit value be estimated, then under the control of the analysis control unit (3), a measurement unit (1) repeatedly carries out GC/MS analysis of a sample including the reference compound. A signal intensity calculation unit (23) determines a signal intensity value for the reference compound on the basis of the analysis results. A relative intensity calculation unit (24) calculates a relative standard deviation from a plurality of measured signal intensity values and calculates, from the relative standard deviation and a response factor for a target compound that has been read from the response factor storage unit (22), the relative standard deviation of the target compound. An analysis limit value estimation unit (25) estimates, for example, a detection lower limit value using a known method on the basis of the relative standard deviation of the target compound and displays the same on a display unit (6). As a result, it is possible to simply determine an analysis limit value without measuring a target compound.
