Gas chromatography method for determination of formaldehyde and methanol content in industrial formaldegyde was set up.The stable analytical conditions were obtained by optimal experiment,and system error was also compared through gas chromatography and titration analysis.Analysis time was saved obviously by using improved GC method,and accuracy and precision were also improved clearly.
