Abstract
Systems and methods are described to concentrate a remote sample for analysis. A sample concentration system embodiment includes, but is not limited to, a plurality of valves including at least a first valve, a second valve, and a third valve; a plurality of columns including at least a first column and a second column, the first column fluidically coupled to the first valve, the second column fluidically coupled to the second valve; and a flow meter coupled with the third valve, the flow meter fluidically coupled with each of the first column and the second column when the plurality of valves is in a first flow path configuration to measure an amount of the liquid sample passed through the first column and the second column, wherein the plurality of valves includes a second flow path configuration and a third flow path configuration.
