Analyzing method for azo compound |
| abstract |
A large number of kinds of azo compounds which are representative hazardous substances in fiber products are divided into two groups. The compounds included in the first group are detected by an MRM measurement by a tandem mass spectrometer unit (12) in a measurement section (10) while a two-liquid gradient elution under an acidic condition is performed in a liquid chromatograph unit (11), using an aqueous ammonium acetate solution as mobile phase A, and a mixture of acetonitrile and an aqueous ammonium acetate solution as mobile phase B. On the other hand, the compounds included in the second group are detected by an MRM measurement while a two-liquid gradient elution under a neutral or weakly basic condition is performed using an aqueous ammonium bicarbonate solution as mobile phase A and acetonitrile as mobile phase B. An exhaustive quantitative analysis for major azo compounds can be achieved by performing the two analyses for the same sample. An efficient test with a shortened analysis period can thereby be performed. |
