Major Research Issues
Development of analytical methods for high accuracy and traceability in inorganic and organic chemistry e.g. determination of trace elements in water and biological material by isotope dilution inductively coupled plasma mass spectrometry (ID-ICP-MS); and determination of perfluoroalkyl acids and hormones using isotope dilution LC-MS/MS.
Development and testing the reliability of field measurement sensors applied for in-situ and on-line environmental measurements. Testing and research of the use of Unmanned Aerial Vehicles (UAV) for environmental monitoring. Development of measurement uncertainty estimation and proficiency testing protocols for field measurements.
