Abstract
The procedures of amperometric and potentiometric determination of chromium, manganese, vanadium and cerium in raw and materials of metallurgical production using a weight automatic titrator «TITRION» have been developed and implemented at the Research center of the Institute for Certified Reference Materials (ICRM). The use of the device provides automation of the titration along with collection of information and data processing which reduces the labor costs, shortens the analysis time, and improves the metrological characteristics. The developed methods, included in the branch and Federal Register, cover almost the entire range of the state standard reference samples of the raw and materials of metallurgical production in a wide range of detectable concentrations and match the metrological requirements.
