"HG/T 6086-2022 Determination of phenol and bisphenol A in Spinning & weaving dyeing and finishing aids" specifies the determination method of phenol and bisphenol A in Spinning & weaving dyeing and finishing aids products. This document is applicable to the quantitative analysis of phenol and bisphenol A in various Spinning & weaving dyeing and finishing aids products. The standard uses methanol as the extraction solvent to extract the target substance in the sample under ultrasonic conditions. After being filtrated, it is detected by a high-performance liquid chromatograph diode array Detector, and the external standard method is used for quantification. In order to ensure the accuracy and Reliability of the determination, the standard refers to the analytical laboratory water mass standard and the numerical revision rule.
