Methanol dehydration is an important process in isobutylene production process, so accurate determination of water content in methanol is the main indicator of production control. However, the conventional method for the determination of methanol water content is not perfect and the reproducibility is poor.

        Filling column determination of trace moisture, chromatographic peak tailing serious, low sensitivity, quantitative error, or even impossible to quantify.

        Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, Institute of Chromatography, analysis and testing center, three scientific research units , Developed GC-790T capillary thermal conductivity detector gas chromatograph determination of trace moisture, water peak symmetry, quantitative and accurate.
