1. Development, optimization, and validation of new calibration and measurement methods according to the requirements of the international standard ISO/IEC 17025.
2. Measurements of amount of substance/concentration in different matrices, with metrological traceability ensured, by the following methods:
- gas chromatography with flame ionization detection;
- gas chromatography with mass spectrometric detection;
- thermal desorption – gas chromatography with mass spectrometric detection (for VOCs identification);
- liquid chromatography with spectrophotometric detection (UV/Vis);
- liquid chromatography with mass spectrometric detection;
- elemental and isotopic analysis.
3. Certification of reference materials according to the requirements of the international standard ISO 17034.
4. Organization and assessment according to requirements of the international standard ISO 17034 of interlaboratory comparisons (ILC) and proficiency tests (PT).
5. Consultations on various issues of chemical measurements and metrological traceability as well as ensuring quality in the field of chemistry.
