Abstract

The triangle-programmed coulometric titration brings about the highly precise and reliable coulometric titrations with the advantages such as reproducible timing, high sampling rate and inexpensive automation. However dispersion in the analysis channel produces tailing which causes deviations from theoretically expected titration curves. When this can not be neglected calibration is necessary. In the paper some theoretical considerations for tailing reduction are describerd. Modified functional parts of flow through analysis channel have been constructed and the reduction of tailing was experimentally proved. With the modified analysis channel much better fit could be achieved between the theoretical and experimental curves even at shorter titrations times. With this improvement considerably smaller consumption of sample- and electrolyte solutions and higher sampling rates were attained.
