滕州市浩瀚色谱仪器技术服务有限公司，根据PET的不溶性,采用液上气体色层分析方法对PET切片中的乙醛含量进行了定量分析。、本方法由德国K·F公司提供,适用于PET切片中乙醛含量定量分析。此方法把样品经粉碎、称量、密封于试样瓶中加热使乙醛由切片中逸出,顶部空间取样气色相谱分析。经我们两年实测证明,分析重现性好,结果准确。



Determination of acetaldehyde in polyethylene terephthalate
Determination of acetaldehyde in polyethylene terephthalate Details:

Stationary phase: polystyrene porous polymer microspheres
Specification: 2,2m*6.35mm
Material: stainless steel / glass
Model: PQ
application:
Determination of residual acetaldehyde content in polyethylene terephthalate (PET) resins for plastic bottles.

GB/T 17931-2018 polyethylene terephthalate (PET) resin for bottles

Determination of acetaldehyde in polyethylene terephthalate

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. based on the insolubility of PET, quantitative analysis of acetaldehyde content in PET sections by liquid gas chromatography. This method is provided by K·F Company of Germany and is suitable for quantitative analysis of acetaldehyde content in PET chips. In this method, the sample is pulverized, weighed, and sealed in a sample bottle to heat, so that acetaldehyde escapes from the slice, and the head space is sampled for gas color phase spectrum analysis. After two years of actual test, the analysis has good reproducibility and accurate results.
