摘要

Methanol, the simplest alcohol that exists, is a colourless, low-density, flammable and water-miscible liquid. Methanol and water have similar properties because both have hydroxyl groups that can form hydrogen bonds. These two solvents form hydrogen bonds with each other, being perfectly miscible in all proportions. The high polarity of methanol makes it a very good solvent for polar substances. These characteristics make it one of the most used solvents in liquid chromatography. In this technique, the absorbance of the mobile phase is one of the critical points in the choice of solvent: the lower the absorption of the solvent, the greater the accuracy of the test and the better results under conditions of gradient elution.
