名稱：毛細(xì)管柱

固定液：聚乙二醇

規(guī)格：30m*0.32mm*0.25um

型號(hào)：PEG-20M

為進(jìn)一步準(zhǔn)確檢測熱灌裝用PET瓶中乙醛含量,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司建立了使用毛細(xì)管柱法測定熱灌裝用PET飲料瓶中乙醛含量氣相色譜方法,并研究了存放條件及使用溫度對乙醛釋放的影響。結(jié)果表明:普通儲(chǔ)存溫度條件,乙醛釋放很緩慢,而強(qiáng)光照射的條件下,會(huì)加速乙醛釋放;灌裝后1h內(nèi)溫度降低到80℃以下,則不會(huì)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.
