Disclosed herein is a device and method for changing the conditions of a solution flowing in a serial path. In particular, disclosed herein is a device that includes a chemical reactor, a first system, and a second system that are each serial to one another. Each of the first system and the second system include a mixing chamber, a solvent reservoir, a solvent pump, and one or more detectors. Also disclosed herein is a method for changing the condition of a solution that includes flowing a liquid sample in a path, serially mixing the sample with at least two discrete solvents while it flows through the path, and detecting the condition of the sample after it is mixed with each solvent.

A first chromatogram is obtained by analyzing a second standard sample by size exclusion chromatography analysis using a first detector. Also, a second chromatogram is obtained by analyzing a solvent for the second standard sample by size exclusion chromatography analysis using the first detector. Then, from the difference between the first chromatogram and the second chromatogram, a third elution time in size exclusion chromatography analysis of the second standard sample using the first detector is determined.

Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.
