A Device For Stepwise Addition Of Titrant In Automated Potentiometric Titrations

A microcomputer-based liquid-propulsion system is described for the stepwise addition of titrant. It is capable of supplying up to six titration cells simultaneously. In titrations of 0.01 M hydrochloric acid with 0.1 M sodium hydroxide, the relative standard deviation was ± 0.1% and the error was +0.2%. © 1989.2221379384Smit, Smit, (1982) Anal. Chim.
