顶空-气相色谱法同时测定塑料类快递封装用品中15种有机溶剂残留量
Simultaneous Determination of 15 Residual Organic Solvents in Plastic Express Packages by Headspace-Gas Chromatography
摘要
Abstract
The potential residual solvents methanol,ethanol,acetone,isopropyl alcohol,dichloromethane,n-hexane,ethyl acetate,isobutanol,isopropyl acetate,n-butanol,toluene,n-butyl acetate,p-xylene,o-xylene,benzene,etc were analyzed and tested by headspace gas chromatography(HS-GC).The method was separated by DB-624(30 m×0.25 mm,1.8 µm)chromatographic column,hydrogen flame ionization detector,optimized conditions,split ratio of 20∶1.The flow rate of carrier gas was 1.5 mL/min,the equilibrium temperature of chromatographic column samples was 100℃,and the headspace equilibrium time was 30 min.The 14 solvents could be completely separated,the correlation coefficients of each object were above 0.999,and the detection limit of test results was between 0.001 and 0.004 mg/m2.The recoveries ranged from 87.05%to 114.07%,and the RSD ranged from 3.16%to 6.60%.The method is easy to operate and has good reproducibility.It is a perfect supplement to the national standard method,and can be used for the daily detection of residual solvent in plastic express packages,providing a reliable basis for quality control.关键词
