Claim Text:
1. A multi-dimensional liquid analysis system, comprising: a first separation system including a first separation column, the first separation column configured to chromatographically separate a liquid mobile phase into a first dimension outflow having a first outflow rate; a flow splitter coupled with the first dimension outflow, the flow splitter configured to separate the first dimension outflow into a first split outlet flow and a second split outlet flow; a second separation system including a second separation column, the second separation column configured to chromatographically separate the second split outlet flow; and a flow control pump fluidly coupled to the flow splitter and configured to withdraw the second split outlet flow from the flow splitter at a controlled withdrawal flow rate to obtain a representative sampling of compounds in the first dimension outflow for separation of the second split outlet flow in the second separation system.
