气相色谱-串联质谱法测定涂料中10种苯并三唑类紫外线吸收剂
|
摘要
建立了涂料中10种苯并三唑类紫外线吸收剂的气相色谱-串联质谱(GC-MS/MS)检测方法。水性涂料和溶剂型涂料样品风干成膜后分别以正己烷、乙腈超声提取,DB-5色谱柱(30 m×0. 32 mm×0. 25μm)分离,MRM模式进行分析检测。结果表明,10种苯并三唑类紫外线吸收剂在0. 1～10μg/m L范围内与峰面积呈线性关系,方法的检出限(S/N=3)为0. 6 mg/kg,定量下限(S/N=10)为2. 0 mg/kg,在2、20、200 mg/kg加标浓度下的回收率为71. 6%～112%,相对标准偏差(RSD,n=6)不大于5. 5%。该方法快速简便、准确可靠,适用于涂料中苯并三唑类紫外线吸收剂的日常分析检测。
A gas chromatography-tandem mass spectrometric( GC-MS/MS) method was developed for the determination of 10 kinds of benzotriazole ultraviolet absorbents in coatings. Samples were air-dried into a film,then extracted with hexane or acetonitrile through ultrasonic method. The target ingredients were separated on a DB-5 column( 30 m × 0. 32 mm × 0. 25 μm) and analyzed under MRM mode. The linear ranges for 10 kinds of benzotriazole ultraviolet absorbents were between 0. 1μg/m L and 10 μg/m L. The limits of detection of this method were 0. 6 mg/kg,and the limits of quantitation were 2. 0 mg/kg. The recoveries ranged from 71. 6% to 112% with relative standard deviations( RSDs,n = 6) not more than 5. 5%. This method was rapid,convenient,accurate and reliable,and it was appropriate for the routine determination of benzotriazole ultraviolet absorbents in coatings.
