AbolishedDetermination of harmful substances in textile dyeing and finishing auxiliaries - Part 4: Determination of polycyclic aromatic hydrocarbons - GC/MS method
纺织染整助剂中有害物质的测定 第4部分：稠环芳烃化合物(PAHs)的测定 气相色谱-质谱法
Application Summary AI generated
This standard specifies a gas chromatography-mass spectrometry (GC/MS) method for determining polycyclic aromatic hydrocarbons (PAHs) in textile dyeing and finishing auxiliaries. It is applied by chemical manufacturers and textile testing laboratories to quantify PAH content in products such as surfactants, leveling agents, and softeners used in textile processing. The standard ensures compliance with regulatory limits on carcinogenic PAHs in auxiliaries, supporting quality control and environmental safety in the textile industry.
