名称L毛细管柱
规格：30m*0.32mm*0.25um
型号：HH-INNOWAX
应用：食品接触材料 高分子材料 苯乙烯单体的测定 气相色谱法

滕州市浩瀚色谱仪器技术服务有限公司，提出了液体顶空-气相色谱法测定食品接触苯乙烯聚合物中残留单体及溶剂的方法。采用N,N-二甲基乙酰胺溶解聚合物,使其中残留单体及溶剂完全释放,并在优化的工作条件下,以基体匹配校正法绘制工作曲线,有效消除基质效应。7种分析物检出限（3S/N）在0.2～4.1mg.kg-1之间。测得方法的回收率在93.2%～103.2%之间,测定值的相对标准偏差（n=6）在1.1%～5.6%之间。

Food material polymer material styrene monomer
Food material polymer material styrene monomer Details:


Name L capillary column
Specification: 30m*0.32mm*0.25um
Model: HH-INNOWAX
Application: Food contact materials, polymer materials, determination of styrene monomer, gas chromatography

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has proposed a liquid headspace-gas chromatography method for the determination of residual monomers and solvents in food contact styrene polymers. N,N-dimethylacetamide is used to dissolve the polymer to completely release the residual monomer and solvent. Under optimized working conditions, the matrix matching correction method is used to draw the working curve to effectively eliminate the matrix effect. The detection limit (3S/N) of 7 analytes is between 0.2～4.1mg.kg-1. The recovery rate of the measured method is between 93.2% and 103.2%, and the relative standard deviation (n=6) of the measured value is between 1.1% and 5.6%.
