| Abstract: | The paper was made gas chromatography of direct measurement infinitesimal ethanol in industrial methanol by us-ing optimum theory of Levenberg—Marqurdt. The results indicated that determining infinitesimal ethanol in industrial methanol by using gas chromatography had advantages of high accuracy, good reproducibility and user-friendly control. The relative standard deviation （RSD） of the method was 〈2.06% （n=5）, the recovery rate was 95.20% to 100.61%. |
