Evaluation of acid-base titration curves obtained by the triangle-programmed titration technique in flowing solutions

Different evaluation techniques for triangle-programmed coulometric acid—base titration curves obtained with various detector systems are compared. In the case of potentiometric detection, hardware differentiation and linearization of the titration curves was investigated. Photometric end-point detection with single or mixed indicators was also studied. It was concluded that among the techniques studied the hardware potentiometric differentiation and the photometric detection with an indicator mixture are the most advantageous.
