Abstract
The following six methods included in a method package for hazardous substances in fiber products is stored beforehand in a method storage section (26): simultaneous analysis method for specific aromatic amines, simultaneous analysis method for the first group of azo dyes, simultaneous analysis method for the second group of azo dyes, simultaneous analysis method for PFCs, simultaneous analysis method for AP, and simultaneous analysis method for APEO. Each analysis method includes analysis conditions and parameters which are suitable for a simultaneous analysis of a specific category of hazardous substances, e.g. azo dyes. An analysis condition setter (25) lists the six analysis methods on a display unit (28), from which an operator selects one analysis method to be executed. The operator also prepares mobile phases and a column specified for each analysis method. An LC controller (23) and an MS controller (24) control each relevant section of the system according to the analysis conditions and parameters described in the selected analysis method, to analyze a sample prepared from a fiber product. By this analysis, a test for major hazardous substances in the fiber product can be p…
