| 摘 要： | 建立了采用超声波提取-气相色谱质谱联用仪检测笔墨水或吸墨笔芯中乙二醇的方法。通过以甲醇为溶剂，超声波萃取笔墨水或吸墨笔芯中的乙二醇，气相色谱质谱联用仪测定，内标法定量，检出限为3 mg/kg，定量限为10mg/kg，加标回收率为95%-102%，相对标准偏差不大于5%，线性范围为10mg/L-500mg/L，相关系数大于0.999。实验结果表明方法简便、可靠，能满足文具笔墨水及吸墨笔芯中乙二醇的检测要求。

| Abstract: | An analytical method for the determination of ethylene glycol in ink or ink refill by Ultrasonic Extraction-GC-MS was established. The sample was extracted with methanol and detected by GC-MS. The LOD of method was 3 mg/kg and the LOQ was 10mg/kg. The recoveries were in the range of 95%-102%, and the relative standard deviations, no more than 5%. The standard curves for ethylene glycol was linear in the concentration range of 10mg/L-500mg/L. |
