Analysis of 21 Antiknock Additives in Gasoline by Comprehensive Two-dimensional Gas Chromatography-Time-of-flight Mass Spectrometry
A comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry was established for the detection of 21 antiknock additives in gasoline.The instrument analysis conditions and quantitative parameters were optimized. Taking full advantage of the superiority in column capacity and separation ability of comprehensive two-dimensional gas chromatography,21 antiknock additives,including 10 alcohols,5 ethers,3 esters,2 amines and 1 ketone,were detected simultaneously.The quantitative accuracies for low concentration samples were improved by weighted least square method.Results showed that there were good linear relationships for 21 additives in the concentration range of 50-10 000 mg/L,with their correlation coefficients(,r,2,)greater than 0.995.The recoveries at four concentration levels of 0.5%,2.0%,5.0% and 10.0% ranged from 91.1% to 109%,with the relative standard deviations(RSDs, ,n ,= 6)less than 5.0%.The limits of detection(,S,/,N ,≥ 3)and the limits of quantification(,S,/,N ,≥ 10)were in the range of 0.000 4%-0.014 1% and 0.001 4%-0.046 9%,respectively.This method could satisfy the requirements for detection of antiknock additives in actual samples.
