GB/T 43721-2024 "Spinning & weaving products, determination of benzalkonium chloride" specifies the use of high-performance liquid chromatograph-diode array Detector (HPLC-DAD) or high-performance liquid chromatograph-tandom mass spectrometer (HPLC-MS/MS) method for the determination of benzalkonium chloride in Spinning & weaving products. The standard applies to all kinds of Spinning & weaving products. The test principle is to extract benzalkonium chloride in samples by acetonitrile ultrasound, after being filtrated by an filtrate membrane, use HPLC-DAD or HPLC-MS/MS for quantitative determination, using External standard method.
