乙醇是甲醇的同系物，其物理化學(xué)性質(zhì)與甲醇很相近，加之精細甲醇的純度很高（99．96％以上），主峰很寬，容易掩蓋乙醇峰，而且在多數(shù)固定液上，乙醇峰是在甲醇峰之后流出，受主峰影響嚴重，這就使得甲醇中微量乙醇的分析成為一個難題。國內(nèi)現(xiàn)在很多企業(yè)都采用GB338—2004標準進行此項分析。

?

GB_338-2004_工業(yè)用甲醇中微量乙醇的測定，甲醇出完峰需要30分鐘左右，分析時間太長，效率低下，無法滿足生產(chǎn)檢測的需要。

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.
