dc.descriptionThe high-performance microcomputer controlled gravimetric-burette described in Part 1 has been employed to automate some routine analytical procedures, A direct potentiometric determination of fluoride ions in drinking water was developed to include an automatic calibration step, matrix adjustment and sample determination. Also the complex and cumbersome titrimetric procedure far determination of the kappa number (lignin content) in paper pulp, has been automated by using the gravimetric unit and biamperometry, In this last instance, the,automatic standardization of the solutions employed in the determination and the complete automation of the recommended kappa number determination procedure, allows a significant reduction in the amount of reagent consumed. The gravimetric approach to these procedures reveals that the same performance is achieved in terms of precision and accuracy when compared with classic volumetry while the cost associated with the automation decreases owing to the use of the same unit to attain automatic management of up to three different solutions.
