Rapid Determination of Ethylene Oxide Residues in Ice Cream by Headspace-Gas Chromatography
Rapid Determination of Ethylene Oxide Residues in Ice Cream by Headspace-Gas Chromatography Details:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the rapid determination of ethylene oxide residues in ice cream by headspace-gas chromatography. Method: Prepare the ice cream sample to be tested, inject the sample into an automatic headspace sampler, connect to an Agilent 4890 gas chromatograph, use Chromosorb 101 HP 60-80 mesh; glass column length 2m*3 mm, temperature programmed for component separation, FID Detector detection, external standard method for quantification. RESULTS: At 0.1～5.0 mg/L, the correlation coefficient of ethylene oxide was greater than 0.999, the recovery of standard addition was 85.7%～100.8%, and the RSD was 1.2%～2.6%. Conclusion: The method effectively reduces the escape of ethylene oxide caused by the operation process, and there is no interference near the target peak, and the recovery and repeatability meet the requirements. It can be used for the detection of ethylene oxide in ice cream.
