Application:
A standard sample of the composition of an aqueous solution of zinc ions is used:
- For calibration of measuring instruments (SI) designed to determine the content of zinc ions by spectrophotometric, polarographic, voltammetric and atomic absorption methods in aqueous media, environmental objects, chemical and food products;
- To control the metrological characteristics of SI during their testing, including for the purpose of type approval;
- For the certification of measurement methods and control of the accuracy of the results of measurements of zinc ion content by spectrophotometric, polarographic, voltammetric and atomic absorption methods in aqueous media, environmental objects, chemical and food products.
CO can be used for verification and calibration of appropriate measuring instruments, provided that its metrological and technical characteristics meet the criteria established in the methods of verification and calibration of appropriate measuring instruments.
Technical specifications:
- The mass concentration of zinc ions is 1.00 g/dm3;
- The limits of the relative error of the certified CO value at P = 0.95 are ± 1.0 %;
- Background 1M HNO3 (the standard sample is a zinc solution in 1 M nitric acid).
The shelf life of a copy of CO is 3 years.
Basic equipment:
