AN AUTOMATIC RECORDING TITRATOR

An automatic recording titrator is described which is applicable to all types of potentiometric titrations. Particular attention has been paid to the maintenance of accurate potential recording of the entire titration curve as well as accurate recording of the volume of titrant used. As a result the instrument is well-suited for analytical research where the complete curves rather than just the equivalence point of the titration is of interest. Simplicity of the instrument is maintained by use of commercially available components for the major functions of amplifying and recording. Each of the major components retains its separate identity, and thus may be used for other applications without alterations. Acceptable substitutes for each of the major components are suggested, and the relative merits of each are discussed. Suggestions for improving the instrument are also discussed. (auth)
