no. 1 Embodiment approach -

[0022] The analysis method of this embodiment is an analysis method for the target substance in a sample that may contain the target substance and the decomposition source substance, and includes generating information on the amount or concentration of the target substance based on the detected concentration of the decomposition source substance. This information is referred to as analysis information. Based on the relative response factors for the decomposition source substance and the specified compound, the concentration of the decomposition source substance is calculated. This predetermined compound is called a reference compound.

[0023] (about the sample)

[0024] The sample is not particularly limited as long as it may contain the target substance and the decomposition source substance. The target substance and the decomposition source substance are not particularly limited as long as it is possible to generate the target substance by decomposing the source substance...

Deformed example 1

[0104] In the above-described embodiment, in the first determination, when the concentration of the decomposition source substance is equal to or greater than the first threshold, the concentration of the target substance or the second threshold is corrected. However, the first threshold may be set as an intensity value, and the first determination may be performed based on whether or not the intensity of the decomposition source substance obtained from the measurement data is equal to or greater than the first threshold. In this case, although the concentration of the decomposition source substance is not required in the first determination, the output unit 43 can output the concentration of the decomposition source substance calculated using the relative response factor as described above and provide it to an analyst or the like.

Deformed example 2

[0106] In the above embodiment, when the decomposition source substance contains at least one of TOTM and n-TOTM, it can be determined based on whether PVC or a compound derived from PVC (hereinafter referred to as PVC, etc.) is detected in the analysis of the sample. Determine whether to perform the first judgment. When PVC or the like is detected, there is an increased possibility that the target substance is generated from TOTM or n-TOTM during analysis. Therefore, by adopting a configuration in which the first determination is performed when PVC or the like is detected, quantitative analysis of the target substance can be performed more efficiently. In this way, the information generation unit 522 can generate analysis information based on whether PVC was detected in the analysis of the sample.

Abstract

The invention relates to an analysis method. This analysis method is a method for analyzing a second substance in a sample containing the second substance, the second substance being generated by decomposition of a first substance, the method comprising: analyzing a sample and a compound having a known concentration to detect a first substance, a second substance and the compound; calculating, on the basis of data obtained from the detection and a relative response coefficient for the first substance and the compound, the strength or the concentration of the first substance obtained from the data; and generating, on the basis of the strength or the concentration of the first substance, information for the amount or the concentration of the second substance, excluding the second substance generated from the first substance during the analysis.

Description

technical field [0001] The present invention relates to an analysis method, an analysis device and a program. Background technique [0002] In analysis such as gas chromatography / mass spectrometry (GC / MS), the introduced substance may be decomposed, and the amount of the substance originally contained in the sample to be analyzed cannot be properly measured. For example, when decabromodiphenyl ether (Deca-BDE) as a flame retardant is mass spectrometered, a reaction product decomposed and generated due to contamination or deterioration of a mass spectrometer is detected. [0003] Therefore, before analyzing the sample of the analysis object, introduce Deca-BDE to the analysis device and detect Deca-BDE and the reaction product to carry out the evaluation of whether the analysis device is in an appropriate state for analysis (refer to non-patent literature 1). [0004] prior art literature [0005] non-patent literature [0006] Non-Patent Document 1: International Electri...
