1 Scope This standard specifies the methods for determining 20 types of allergenic disperse dyestuffs in dyed leathers, furs and their products. This standard is applicable to dyed leather and fur products. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 6682 Water for Analytical Laboratory Use - Specification and Test Methods QB/T 1267 Finished Fur Products - Sample Piece - Position and Marking QB/T 1272 Finished Fur Products - Preparation of Chemical Analysis Sample and General Rules for Chemical Analysis QB/T 2706 Leather - Chemical Physical and Mechanical and Fastness Tests - Sampling Location QB/T 2716 Leather - Preparation of Chemical Test Samples 3 Theory After the sample was extracted with methanol under ultrasonic wave, subject the extract liquor to qualitative and quantitative determination with the high performance liquid chromatography - diode array detector (HPLC/DAD) or the high performance liquid chromatography - tandem mass spectrometry (HPLC-MS/MS). 4 Reagents Unless otherwise specified, the analytically pure reagents and Grade II water (specified in GB/T 6682) are adopted. 4.1 Methanol (chromatographic grade). 4.2 Disodium hydrogen phosphate.
