Abstract
Spectrum images of chromatograph column effluent are formed on a photodiode array (7). The photodiode array (7) is scanned to produce plural detection data for predetermined plural wavelengths. The data are analytically processed and recorded to provide data ratios wherein the numerators are processed data from individual wavelengths, and the denominator in each of the ratios is the square root of the sum of the square of the processed data for the individual wavelengths. A plot of ratios versus time provides a curve which indicates completeness of chromatographic separation.
