Abstract
In a chromatographic analyzer system in which plural detectors in series are utilized, multiplexing of the output from the plurality of detectors is synchronized with pulses provided from a volume counter which provides a precise measurement of the volume of fluid which has flowed through each detector. Such synchronous multiplexing allows the output from the plurality of detectors to be provided to a single data acquisition input without loss of differentiation between the multiple detector outputs. The volume counter is also utilized to provide automatic compensation for fluid volume between the series connected detectors.
