Microcomputer Automation of the Conductometric Titration of Hop Alpha-Acids

A general-purpose microcomputer was used to au tomate the determination of lead conductance value by titration. The microcumputer, presented with an extracted sample in a beaker, controls the addition of titrant and the taking of data, performs all calculations, and finally prints the corrected result along with a record of the titration. A number of operating parameters were studied in order to optimize the titration. The computer system performs the analysis more rapidly than a human operator and permits much more efficient use of the analyst's time.
