PEG-20M毛细管柱 毛细管柱法测定热灌装用PET瓶中的乙醛含量的详细资料

毛细管柱法测定热灌装用PET瓶中的乙醛含量
毛细管柱法测定热灌装用PET瓶中的乙醛含量 详细信息：

名称：毛细管柱

固定液：聚乙二醇

规格：30m*0.32mm*0.25um

型号：PEG-20M

为进一步准确检测热灌装用PET瓶中乙醛含量,浩瀚色谱（山东）应用技术开发有限公司建立了使用毛细管柱法测定热灌装用PET饮料瓶中乙醛含量气相色谱方法,并研究了存放条件及使用温度对乙醛释放的影响。结果表明:普通储存温度条件,乙醛释放很缓慢,而强光照射的条件下,会加速乙醛释放;灌装后1h内温度降低到80℃以下,则不会有乙醛析出。

Determination of acetaldehyde in PET bottles for hot filling by capillary column method
Determination of Acetaldehyde Content in PET Bottles for Hot Fill by Capillary Column Method Details:

Name: capillary column

Fixative: polyethylene glycol

Specifications: 30m*0.32mm*0.25um

Model: PEG-20M

In order to further accurately detect the acetaldehyde content in PET bottles for hot filling, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a gas chromatography method for the determination of acetaldehyde content in PET beverage bottles for hot filling by capillary column method, and studied the method. Effects of storage conditions and operating temperature on acetaldehyde release. The results show that the release of acetaldehyde is very slow under normal storage temperature conditions, while the release of acetaldehyde will be accelerated under the condition of strong light irradiation; after filling, when the temperature drops below 80℃ within 1 hour, there will be no precipitation of acetaldehyde.
