Ethanol is a homologue of methanol, and its physical and chemical properties are very similar to methanol. In addition, fine methanol has a high purity (over 99.96%) and a wide main peak, which easily masks the ethanol peak. Moreover, on most stationary liquids, the ethanol peak flows out after the methanol peak, which is severely affected by the main peak. This makes the analysis of trace amounts of ethanol in methanol a difficult problem. Many domestic enterprises now adopt the GB338-2004 standard for this analysis.
GB_338-2004_ Determination of Trace Ethanol in Industrial Methanol. It takes about 30 minutes for methanol to peak, which is too long and inefficient to meet the needs of production testing.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a new chromatographic column for industrial methanol analysis, which requires only one-third of the standard analysis time and has high efficiency,
Meeting the needs of large-scale industrial production testing, satisfactory test results have been achieved on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE.
