Abstract: In one aspect, a system for adjusting flow rate of at least one mobile phase delivered to a liquid chromatography (LC) column is disclosed, which includes a first plurality of pre-calibrated flow modules each configured to receive a first mobile phase at an inlet port thereof and to provide a pre-calibrated range of output flow rates of said first mobile phase at its outlet port, wherein said first plurality of flow modules are configured to provide different ranges of output flow rates of said first mobile phase, and a first selector valve in fluid communication with said first plurality of pre-calibrated flow modules for selecting among said first plurality of pre-calibrated flow modules for selective delivery of said first mobile phase to said LC column, thereby adjusting the flow rate of the first mobile phase delivered to said LC column.
