摘要: | 目的:建立测定注射用血栓通(冻干)中有机溶剂苯、甲苯、对二甲苯、邻二甲苯、苯乙烯、1,2-二乙基苯、二乙烯苯残留量的方法。方法:采用顶空气相色谱串联质谱法。色谱柱为HP-INNOWAX毛细管柱,程序升温,检测器为质谱,进样口温度为180 ℃,载气为氦气,流速为1.5 ml/min,分流比为2 ∶ 1, 顶空瓶平衡温度为80 ℃,平衡时间为30 min,进样方式为顶空进样,顶空瓶装样量为20 ml,进样量为1 ml。质谱检测器为选择离子检测方式,电离方式为EI,电离电压为70 eV,接口温度为250 ℃,离子源温度为230 ℃,四极杆温度为150 ℃。结果:苯、甲苯、对二甲苯、邻二甲苯、苯乙烯、1,2-二乙基苯、二乙烯苯检测质量浓度线性范围分别为0.020 8~0.832 0、0.107 4~4.297 6、0.088 5~3.539 2、0.104 5~4.128 0、0.103 2~4.128 0、0.090 9~3.635 2、0.096 0~3.840 0 μg/ml(r=0.999 4、0.999 5、0.999 5、0.999 7、0.999 8、0.999 6、0.999 5);精密度、稳定性、重复性试验的RSD<5%;加样回收率分别91.85%~99.06%、96.46%~102.56%、101.49%~106.98%、95.91%~101.73%、93.40%~101.85%、103.11%~111.82%、87.58%~94.66%,RSD分别为2.6%、2.2%、2.0%、2.2%、3.1%、2.9%、3.5%(n=6)。结论:该方法简便、快捷、准确,可用于注射用血栓通(冻干)中有机溶剂苯、甲苯、对二甲苯、邻二甲苯、苯乙烯、1,2-二乙基苯、二乙烯苯残留量的测定。 |
ABSTRACT: | OBJECTIVE:To establish a method for the determination of organic residues of benzene, toluene, p-xylene, o-xylene, styrene, 1,2-diethylbenzene and divinylbenzene in Xueshuantong for injection (freeze-dried). METHODS:HS-GC-MS/MS was performed on the column of HP-INNOWAX capillary column by programmed temperature, the detector was MS, injector temperature was 180℃, carrier gas was helium at a flow rate of 1.5 ml/min, and the split ratio was 2 ∶ 1, headspace bottle equilibrium temperature was 80 ℃, equilibrium time was 30 min; injection way was headspace, sample volume was 20 ml, and the injection volume was 1 ml; MS detector mwas selected ion monitoring, ionization was EI, ionization voltage was 70 eV, interface temperature was 250 ℃,ion source temperature was 230 ℃, and quadrupole temperature was 150 ℃. RESULTS: The linear range was 0.020 8-0.832 0 μg/ml for benzene(r=0.999 4),0.107 4-4.297 6 μg/ml for toluene(r=0.999 5), 0.088 5-3.539 2 μg/ml for p-xylene(r=0.999 5), 0.104 5-4.128 0 μg/ml for o-xylene(r=0.999 7),0.103 2-4.128 0 μg/ml for styrene(r=0.999 8),0.090 9-3.635 2 μg/ml for 1,2-diethylbenzene (r=0.999 6) and 0.096 0-3.840 0 μg/ml for divinylbenzene(r=0.999 5); RSDs of precision, stability and reproducibility tests were lower than 5%; recoveries were 91.85%-99.06%(RSD=2.6%,n=6),96.46%-102.56%(RSD=2.2%,n=6),101.49%-106.98%(RSD=2.0%,n=6),95.91%-101.73%(RSD=2.2%,n=6), 93.40%-101.85%(RSD=3.1%,n=6), 103.11%-111.82%(RSD=2.9%,n=6), and 87.58%-94.66%(RSD=3.5%,n=6), respectively. CONCLUSIONS: The method is simple, rapid and accurate, and can be used for the determination of organic residues of benzene, toluene, p-xylene, o-xylene, styrene, 1,2-diethylbenzene and divinylbenzene in Xueshuantong for injection (freeze-dried). |
