Certified Mixtures

Krastsvetmet’s laboratory produces mixtures in single-element and multi-element solutions, which contain precious metals and other components.

Application of the mixtures:

  • calibration and testing of spectrometers, spectrophotometers, titrators, coulometers;
  • establishing metrological characteristics for methods of quantitative chemical analysis.

Certified mixtures containing precious metals are made of refined metals produced by Krastsvetmet:

  • gold, silver — minimum 99.99%
  • platinum, palladium — minimum 99.98%
  • rhodium, iridium, ruthenium, osmium — minimum 99.97%
