Central Office of Measures Chemistry -

Tasks:

• Realization and development of primary methods of measurement and reference materials of highest metrological level providing traceability to SI in chemical and physicochemical measurements;
• Maintenance and development of the national measurement standards and the reference standards;
• Providing traceability in the area of pehametry, conductometry, gas analysis, atomic absorption spectrometry and IR spectroscopy;
• Participation in national and international interlaboratory comparisons;
• Research works on metrology in chemistry.

Services:

1. Calibration:

• gas analyzers and dissolved oxygen meters,
• gas mixtures,
• pH meters, pH simulators and pH electrodes,
• electrolytic conductivity meters and conductivity cells,
• solid wavenumber standards for IR spectroscopy.

2. Certified reference materials:

• primary and secondary reference materials for pH,
• primary and secondary reference materials for electrolytic conductivity,
• primary reference materials for amount of substance content (high purity substances),
• reference materials for atomic absorption spectrometry (ASA).
