GB/T 34706-2017 "Determination of Organotin Compounds in Coatings by Gas Chromatography-Mass Spectrometry" is applicable to the detection of organotin compounds in coatings. After appropriate extraction and purification pretreatment, the samples are analyzed using a gas chromatography-mass spectrometry system. The target components are separated by a chromatographic column, identified based on retention time and characteristic ion peaks, and quantified by the external standard method. The instrument detection parameters and method precision requirements are specified, providing a standardized testing method for the control of harmful substances such as organotin in coatings.
