HH-PLOT U毛细管柱测定工业甲醇的纯度

HH-PLOT U毛细管柱测定工业甲醇的纯度详细信息:



粗甲醇纯度的测定,一般采用蒸馏法和铬酸氧化法。铬酸氧化法由于操作繁而费时,重复性差,一般很少采用。粗甲醇纯度的测定,以前采用蒸馏法,此法虽属经典方法,但操作条件不易掌握,测定结果不稳,而且由于粗甲醇成分复杂,不易分离,蒸馏过程中甲醇有损失,致使结果偏低。

随着气相色谱法在分析技术上的应用日益广泛,浩瀚色谱采用了FID检测器,HH-PLOT U毛细管柱测定工业甲醇的纯度,结果准确。

Detailed information on the purity determination of industrial methanol using HH-PLOT U capillary column:
The determination of crude methanol purity generally uses distillation and chromic acid oxidation methods. The chromic acid oxidation method is generally rarely used due to its complex and time-consuming operation, poor repeatability. The determination of crude methanol purity used to be done using distillation method. Although this method is a classic method, the operating conditions are not easy to master, and the measurement results are unstable. Moreover, due to the complex composition of crude methanol, it is not easy to separate, resulting in methanol loss during the distillation process and lower results.
With the increasingly widespread application of gas chromatography in analytical technology, Haohan chromatography uses FID detectors and HH-PLOT U capillary columns to determine the purity of industrial methanol, with accurate results.
