Abstract

PURPOSE: To make possible accurate detection of end point by perfoming the end point detection of titration reaction from the change in the tendency of change rate of the potential at the end point of the titration reaction in an automatic titrator.
CONSTITUTION: The signal from a halogen ion detection electrode 1 passes through a gate circuit 2 and is amplified to a constant level by an amplifier 3 and is cut off of noise by a low-pass filter 4, after which it is sent to a primary differenctiation circuit. This signal is further amplified by an amplifier 6 and is cut off of noise by a low-pass filter 7, after which it goes through a secondary differentiation circuit 8 and its zero point is detected with a comparator 9 and this becomes the end point of titration.
