WARNING - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions
It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set forth in the relevant national regulations.
1 Scope
This standard specifies the use of high performance liquid chromatography - fluorescence detector (HPLC-FLD) determination of textile products in nine kinds of fluorescent whitening agent (see attached
Record A) method.
This standard applies to all types of textile products.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 6682 Analytical laboratory water specifications and test methods
3 principle
The samples were placed in a dimethylformamide-water mixture and extracted by sonication. The samples were washed with a high performance liquid chromatograph equipped with a fluorescence detector
(HPLC-FLD). The retention time is used to qualitatively determine the material to be measured, and the external standard method is used to quantify the material to be measured.

4.2 Methanol. Chromatographic purity.
4.3 acetonitrile. pure chromatography.
4.4 Trichloromethane. Chromatographic pure.
4.5 Dimethylformamide. Analytical purity.
4.6 Ammonium acetate. Chromatographic purity.
4.7 70% dimethylformamide-water mixed solution (volume ratio). take 700mL dimethylformamide, add water to volume to 1000mL, mix
