目的:建立一种测定装饰装修用溶剂型胶粘剂中挥发性有害化合物的GC-MS方法。方法:称取适量胶粘剂样品,用乙酸乙酯定容至50 ml,4000 r/min离心后,用GCMS全扫描定性,选择离子定量。结果:线性相关系数>0.9995,检测限0.006μg/ml～0.14μg/ml,最低检测浓度0.001 mg/kg～0.029 mg/kg。结论:采用气相色谱-质谱联用仪检测装饰装修用溶剂型胶粘剂中7种挥发性有机物,分离好,灵敏度高,特异性强,检测快速。
Objective: To establish a GC-MS method for the determination of volatile and harmful compounds in solvent-borne adhesives. Methods: Weigh an appropriate amount of adhesive samples, with ethyl acetate volume to 50 ml, 4000 r / min after centrifugation, qualitative GCMS scanning, select ion quantification. Results: The linear correlation coefficient> 0.9995, the detection limit of 0.006μg / ml ~ 0.14μg / ml, the lowest detection limit of 0.001 mg / kg ~ 0.029 mg / kg. Conclusion: Seven kinds of volatile organic compounds in solvent-based adhesives for decorating and decorating are detected by gas chromatography-mass spectrometry. The results show good separation, high sensitivity, high specificity and rapid detection.
