Abstract
Automatic titrators are designed to do exactly what a lab‐technician used to do. Much more sophisticated automation of volumetry is possible. Omegaphoresis [3] in buffer‐free [2] sample solutions automatically creates a stationary multiple component titration curve or zoned pattern with normalized concentrations of each separated species. An automatic measurement of each zone length yields their quantity. Simultaneous automatic detection of all the zones in a 10–20 component solution in less than 2 minutes, with a precision of ±2%, a required amount of the order of less than one nanomol and a resolution of ±pK < 0.01 replaces acid‐base, complexometric, and certain types of redox‐titrimetry. An option of the method allows identification of the components as well.
