Question

Quizplus · Accepted Answer

The low-pressure mixing pump creates gradients from up to four solvents by proportioning liquids through a four-way valve before the piston and then pumping them into the column. This method is known as low-pressure mixing because the mixing of solvents occurs before the pump pressurizes the liquid for chromatographic separation.
