Applications of Automatic Titration Instruments in the Specialty Metals Industry

Source

Classical volumetric analysis remains an essential service in the modern specialty alloy industry, but now a new generation of automatic titrators can remove some of the tedium and operator-skill factors associated with the technique. Carpenter Technology's recent experience with two commercial instruments is described. The new titrators allow high-speed closed-loop electronic control of potentiometric redox or acid-base titrations in any of several fixed-endpoint or endpoint-seeking modes. Major modification of the basic chemistry of manual titration procedures is usually not required to adapt them to the automatic equipment, although sometimes minor changes are necessary. Applications for the determination of major levels of chromium, vanadium, boron, and cobalt in highly alloyed materials have demonstrated that, when properly configured, these instruments can routinely meet or exceed the performance data for the equivalent manual method in skilled hands.
