…which is registered as a peak on a strip-chart recorder. The recorder trace where solute is absent is the baseline. A plot of the solute concentration along the migration coordinate of development chromatograms yields a similar solute peak. Collectively the plots are the concentration profiles; ideally they are Gaussian (normal,…

…drift, start integration when a peak appears, integrate, and stop the process when the peak exits the detector. Integration, a process of summation, is accomplished by opening and closing a narrow electronic window, registering the signal intensity, repeating the process, and then summing the stored signals to produce a number…
