ABSTRACT:
A method for on-line assay in column chromatography of a property that requires appreciable time for sensitive measurement has the steps of separating the effluent into discrete fractions at equal time intervals, sequentially passing each fraction through each of a series of detectors, while preventing each fraction from mixing with another; and, for each fraction, calculating the assay from the information provided by each detector during the time interval the fraction passed through it.
