ENVICAL Syke – Calibration Laboratory

Short description:

The Syke calibration laboratory produces calibration results with high precision and traceability and is responsible for developing methods based on primary technologies. The Syke calibration laboratory contributes to the maintenance and development of the national measurement standard system and is responsible for the application of the SI system within the scope of the contract laboratory/designated institute.

Major research issues/sites:

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.
