規(guī)格:2,2m*6.35mm
材質(zhì):不銹鋼/玻璃
型號(hào):PQ
應(yīng)用:
SH/T 1817-2017 塑料瓶用聚對(duì)苯二甲酸乙二醇酯(PET)樹脂中殘留乙醛含量的測(cè)定頂空氣相色譜法
GB/T 17931-2018 瓶用聚對(duì)苯二甲酸乙二酯(PET)樹脂
聚對(duì)苯二甲酸乙二醇酯中乙醛測(cè)定 圖片:
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司,根據(jù)PET的不溶性,采用液上氣體色層分析方法對(duì)PET切片中的乙醛含量進(jìn)行了定量分析。、本方法由德國(guó)K·F公司提供,適用于PET切片中乙醛含量定量分析。此方法把樣品經(jīng)粉碎、稱量、密封于試樣瓶中加熱使乙醛由切片中逸出,頂部空間取樣氣色相譜分析。經(jīng)我們兩年實(shí)測(cè)證明,分析重現(xiàn)性好,結(jié)果準(zhǔn)確。
Determination of acetaldehyde in polyethylene terephthalate

nary phase: polystyrene porous polymer microspheres
Specification: 2,2m*6.35mm
Material: stainless steel / glass
Model: PQ
application:
Determination of residual acetaldehyde co

Determination of acetaldehyde in polyethylene terephthalate
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. ba
sed on the insolubility of PET, quantitative analysis of acetaldehyde co
ntent 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 co
ntent 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.
