Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. used gas chromatography to simultaneously determine the content of bing ketone, butanone, in the air of the ship. An air sample containing the above two ketone compounds was collected using an activated carbon tube, desorbed with carbon disulfide, separated with a packed column, and detected by a hydrogen flame ionization detector. Acetone, methyl ethyl ketone, and detection limits (25/N) were 9, 5, L^-1, respectively. The recovery rate of the method is between 87.8% and 105%, the relative standard deviation (n=8) is between 3.6% and 5.2%, and the desorption efficiency is between 88.6% and 98.8%.
