【 摘 要 】

This article has designed a vehicle gasoline on-site sampling and rapid detection device. Automatically taking gasoline samples during gasoline handling, two-dimensional gas chromatographic method is used for the rapid quantitative detection of the unconventional additive methylal. The heavy components are separated by back-blowing to air with the non-polar capillary column while the methylal and light components are separated by a polar column to determine the methylal content. The experiment shows that linear relationship between value of peaks area and mass concentration of methylal is keep in the range of 0.020∼90.0mg/mL with the correlation coefficients of 0.99, and the relative standard deviation (RSD) are less than 2%. The study shows that the limits of detection are 0.012g/L. This device can provide effective means for vehicle gasoline on-site sampling and quality control.
