AUTOMATIC CONTROL OF CHROMATOGRAPHIC FRACTIONATING PROCESSES

As disclosed herein, the angle of optical rotation, concentration, flow rate and temperature of the components such as, for example, glucose and fructose in an aqueous solution emerging from a fractionating process are continuously measured and signals corresponding to the measurements are fed to a...

Beschreibung
Zusammenfassung:	As disclosed herein, the angle of optical rotation, concentration, flow rate and temperature of the components such as, for example, glucose and fructose in an aqueous solution emerging from a fractionating process are continuously measured and signals corresponding to the measurements are fed to a computer. The computer calculates the instantaneous and/or average purity and/or the expected purity of the components and, when predetermined purity values are reached, the computer controls the distribution of the various fractions in accordance with a preset program.
