Automatic titrators are designed to do exactly what a labโtechnician used to do. Much more sophisticated automation of volumetry is possible. Omegaphoresis [3] in bufferโfree [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 10โ20 component solution in less than 2 minutes, with a precision of ยฑ2%, a required amount of the order of less than one nanomol and a resolution of ยฑpK < 0.01 replaces acidโbase, complexometric, and certain types of redoxโtitrimetry. An option of the method allows identification of the components as well.
