| Abstract: | Volatile organic acids and lactic acid in the environmental samples were simultaneously determined by ion exclusion chromatography(IEC) method.The concentration and velocity of mobile phase were examined for the effects to the separation of organic acids.The results showed that lactic acid,formic acid,acetic acid,propionic acid,butyric acid and pentanoic acid were completely separated.The measured concentrations of organic acids showed good linear relationships with those peak heights in a certain range.The... |
