I am using an Agilent Infinity II 1290 Flexible pump and would like to start the gradient profile a fixed time before an injection is made. I am using Empower 3 for acquisition and control. Is there a "simple" way to do this, or is there a trick that can be used? Waters has built this functionality into their instruments with Empower. I am just wondering if it is possible with an Agilent system.
