Both solvents contained 8 μM phosphoric acid, 10 mM ammonium acetate, and 0.1 vol% formic acid. The linear gradient started at 50% solvent B at a constant flow rate of 0.15 ml/min and increased to 100% solvent B within 20 min.

Web10 apr. 2024 · A polar solvent is a liquid with molecules that have a slight electrical charge due to its shape. For example, water is a molecule with one oxygen and two hydrogen atoms. The two hydrogen atoms are not on opposite sides of the oxygen, but rather at an angle. This creates a slight imbalance of the electrical charge in the water molecule, also … WebSolvent Density mp bp MW Polarity Water solub.
