Granularity: 60-80 mesh
Application: SH/T1817-2017 Determination of Residual Acetaldehyde Content in Polyethylene Terephthalate (PET) Resin for Plastic Bottles by Headspace Gas Chromatography

According to the insolubility of PET, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used the liquid gas chromatography method to quantitatively analyze the acetaldehyde content in PET slices. It is suitable for quantitative analysis of acetaldehyde content in PET slices. In this method, the sample is crushed, weighed, sealed in a sample bottle and heated to make acetaldehyde escape from the slice, and the headspace is sampled for gas chromatography analysis. After two years of actual measurement, it is proved that the analysis has good reproducibility and accurate results.
