摘　　要：使用中等极性DB-624色谱柱,建立一种气相色谱-质谱法检测纸质包装材料中18种光敏引发剂含量的方法;探讨载气流量、色谱柱温度对18种光敏引发剂分离性能的影响。研究结果表明:该气相色谱-质谱检测方法的校正曲线呈现出良好的线性关系,R^(2)>0.99;检出限为0.09~0.32 mg/m^(2),定量限为0.32~1.06 mg/m^(2),回收率为82.78%~114.03%。因此该检测方法切实可行,检测结果准确可靠。For determination of 18 photoinitiators(PIs)in paper packaging by gas chromatograph-mass spectrometry(GC-MS),a method with medium polar column(DB-624)was developed.The influences of carrier gas flow rate and column temperature on the separation performance of 18 PIs were studied.The results showed that the calibration curve of the GC-MS method indicated a good linear relationship,with R^(2)>0.99,the limits of detection range within 0.09~0.32 mg/m^(2),the limits of quantification range within 0.32~1.06 mg/m^(2),and the recoveries between 82.78%~114.03%,which proved that the method is feasible,accurate,and reliable.
