Chromatography – Elution chromatography: This method, employed with columns, involves solute migration through the entire system and solute detection as it emerges from the column. The detector continuously monitors the amount of solute in the emerging mobile-phase stream—the eluate—and transduces the signal, most often to a voltage, which is registered as a peak on a strip-chart recorder.
