Method for high pressure gradient chromatography using pump stroke control

Generating a flow having a composition gradient, such as a mobile phase gradient for liquid chromatography, by initiating a plurality of pump strokes from first and second pumps 38, 50 contributing respective first and second liquids A, B, such as solvents, to the composition gradient of the flow, t...
