1. A quantitative determination device for brominated flame- retardant compounds, comprising:
a storage section holding a relative response factor which represents a relationship of an intensity per unit quantity of a compared compound measured by a predetermined analyzing method under a predetermined condition, to an intensity per unit quantity of a reference compound measured by thea predetermined analyzing method under the predetermined condition, where the reference compound is one of a plurality of target compounds which constitute a portion or an entirety of a group of polybrominated biphenyls and polybrominated diphenyl ethers, while the compared compound is one of the target compounds different from the reference compound;
an analyzer configured to analyze a sample by the predetermined analyzing method;
a standard-sample measurer configured to acquire an intensity of the reference compound by performing a measurement of a standard sample under the predetermined condition, using the analyzer, with the standard sample containing the reference compound in known quantity;
a target-sample measurer configured to acquire intensities of the reference compound and the compared compound contained in a target sample by performing a measurement of the target sample under the predetermined condition, using the analyzer;
a reference-compound quantity determiner configured to determine a quantitative value of the reference compound contained in the target sample, based on the quantity of the reference compound contained in the standard sample, the intensity of the reference compound acquired by the standard-sample measurer, and the intensity of the reference compound acquired by the target-sample measurer; and
a compared-compound quantity determiner configured to determine a quantitative value of the compared compound, based on the quantity of the reference compound contained in the standard sample, the intensity of the reference compound acquired by the standard-sample measurer, the intensity of the compared compound acquired by the target-sample measurer, and the relative response factor of the compared compound.
