Expansion of the GSO Zinc line!

11.02.2025

We are pleased to announce the expansion of our range of
State Standard Zinc Samples
and introduce a new, convenient packaging - 40 ml!

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 zinc ion content 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 type approval purposes;
For certification of measurement methods and control of accuracy of zinc ion content measurements by spectrophotometric, polarographic, voltammetric and atomic absorption methods in aqueous media, environmental objects, chemical and food products;
For verification and calibration of the relevant measuring instruments, provided that its metrological and technical characteristics meet the criteria established in the verification and calibration methods of the relevant measuring instruments.
