| Abstract: | The impurity of m-xylene in p-xylene was completely separated on a PEG-20M capillarycolumn with FI detector. The effect of analysis conditions on results was disclissed,and therelative correction factor of m-xylene determined, thus achieving accurate quantitativeanalysis of 0.1% 2% m-xylene in p-xylene. |
