Molecular formula :
nature : change process known as solvent elution (solvent elution programming). Liquid Chromatography important program control technology. Intermittent or continuous change of the mobile phase composition, thereby changing its elution chromatography methods of elution. Improve the complex sample separation, reduce analysis time, improve peak shape and peak detection sensitivity. Gradient elution can be ladder-style, linear, and can also be indicators of the type.
