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.
