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%.
