3 Terms and definitions

There are no terms and definitions that need to be defined in this document.

4 Principle

After the sample was extracted with acetonitrile, centrifuged, diluted and filtered, it was determined by liquid chromatography-tandem mass spectrometry and quantified by external standard method.

5 Reagents and materials

Unless otherwise specified, all reagents used are of analytical grade. 5.1 Water. GB/T 6682, level one. 5.2 Acetonitrile. chromatographically pure. 5.3 Ammonium acetate. chromatographically pure. 5.4 Trichloromethane. chromatographically pure. 5.5 5mmol/L ammonium acetate solution. accurately weigh 0.3854g of ammonium acetate (5.3), dissolve in water and dilute to 1L. 5.6 Standard material. English name, CAS number, molecular formula, and relative molecular mass of fluorescent whitening agent 367 and fluorescent whitening agent 393 standard materials The quantity and chemical structure formula are shown in Table A.1 in Appendix A, and the purity of each standard substance is not less than 98%. 5.7 Mixed standard intermediate working solution. accurately weigh appropriate amount of standard substance (5.6) (accurate to 0.1mg), and use chloroform (5.4) to prepare A single-label standard stock solution with a mass concentration of 100μg/mL was prepared (stored at 4°C and protected from light for 3 months). Accurately transfer each single label 0.25mL of quasi-stock solution, placed in a 25mL brown volumetric flask, and dilute with acetonitrile (5.2) to prepare a mixed standard intermediate working solution (each is 1.0μg/mL, ready to use). ......
