建立了测定染料产品中有害溶剂含量的气相色谱(外标法)检测方法。用气相色谱对样品中的有害溶剂及其他有机组分进行分离,用峰面积外标法进行定量。通过气相色谱-质谱联用仪对有害溶剂进行了定性。样品的加标回收率为90%~110%;有害溶剂检测的相对标准偏差小于1%。结果显示,该方法线性良好,回收率、精密度好,灵敏度高,符合检测要求。
A gas chromatography (external standard method) method for the determination of harmful solvents in dye products was established. Using gas chromatography on the sample of harmful solvents and other organic components were separated by peak area external standard method for quantification. Hazardous solvents were characterized by gas chromatography-mass spectrometry. The spiked recoveries of samples ranged from 90% to 110%. The relative standard deviations of harmful solvents were less than 1%. The results show that this method has good linearity, good recovery, good precision, high sensitivity and meets the testing requirements.
