提出了气相色谱-质谱法测定塑料和电子电气产品中N-乙烯基吡咯烷酮的含量的方法。样品1.000 0 g用四氢呋喃10 mL超声提取30 min，提取液经0.45 μm聚四氟乙烯滤头过滤后，采用气相色谱-质谱法进行测定，以DB-624毛细管色谱柱进行程序升温，在全扫描模式下选择m/z 56，111，28，41为定性离子，在选择离子监测模式下以m/z 111为定量离子。N-乙烯基吡咯烷酮的质量浓度在0.05~10 mg·L^-1内与其峰面积呈线性关系，检出限（3S/N）为0.1 mg·kg^-1。按标准加入法进行回收试验，回收率在94.9%~114%之间，相对标准偏差（n=7）在0.040%~1.6%之间。

A method was proposed for the determination of N-vinyl-2-pyrrolidone (NVP) in plastic, electronic and electrical products by gas chromatography-mass spectrometry (GC-MS). The sample of 1.000 0 g was extracted ultrasonically with tetrahydrofuran of 10 mL for 30 min, and the extract was filtered through PTFE membrane and then determined by GC-MS using DB-624 capillary column for temperature programming. The quanlitative ions (m/z 56, 111, 28, 41) and the quantitative ion (m/z 111) were selected in SCAN and SIM, respectively. linear relationship between values of peak area and mass concentration of NVP was obtained in range of 0.05-10 mg·L^-1 with detection limit(3S/N) of 0.1 mg·kg^-1. Test for recovery was made by standard addition method, giving results in the range of 94.9%-114%, with RSDs (n=7) ranged from 0.040% to 1.6%.
