| 英文摘要 | a novel method based on the technique of capillary column switching-backflushing was developed for the analysis of aromatics in gasoline. the sample was first separated on an ov-2330 polar pre-column where aromatics were retained after n-c-10 and were back flushed onto a non-polar analytical column. the early eluting components from pre-column and the components of interest (aromatics plus heavier compounds) eluting from analytical column were all directed to the same detector through a 't' piece, which permits quantitative analysis of aromatic hydrocarbons in gasoline by factor corrected normalization method. the precision of the analyses were within 3 % rsd. the switching time window was +/- 5 seconds and has miner influence on the result of analysis(rsd less than or equal to 4 %). |
