Determination of Migration of Acetaldehyde in PET Bottled Water
Determination of the migration amount of acetaldehyde in PET bottled water Details:
Name: Capillary Column
Specification: 30m*0.32mm*0.5um
Model: PEG-20M
In life, we can see the use of PET bottles to store food or drinking water. How safe is the use of PET bottles? This article is with such doubts, choosing several common products in life as research samples, and analyzing by chromatography The method detects the acetaldehyde co
ntent in PET bottles, so that the research results can be directly used for practical guidance.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. proposed a gas chromatography-mass spectrometry method to determine the migration of acetaldehyde in polyethylene terephthalate (PEGTP) bottled pure water. The temperature is programmed in the range of 70℃~280℃ Separation. The linear range is within 300 μg·Ll, the detection limit (3S/N) is 1 μg·L-1, and 50 μg·L-1 and 100 μg·Ll standard solutions are added for recovery test and precision test. The average recovery rate was 88%, and the relative standard deviation (n=5) was 5.4% and 4.5%, respectively.
