Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposed a gas chromatography-mass spectrometry method for the determination of acetaldehyde migration in polyethylene terephthalate (PEGTP) bottled pure water. The separation was carried out by using PQ packed column and temperature programming in the range of 140℃～280℃. The linear range is within 300μg·L~(-1), the detection limit (3S/N) is 1μg·L~(-1), adding 50μg·L~(-1) and 100μg·L~(-1) standards The solution was tested for recovery and precision. The average recovery was 88%, and the relative standard deviation (n=5) was 5.4% and 4.5%.
