Scientific Workshop Eurachem 2023

Workshop: Ensuring reliable and accurate results of analytical processes

The analytical process spans from sampling over sample preparation to the actual measurement process. All these steps contribute to the measurement uncertainty of the result. Reliable and accurate results are subsequently interpreted and further used. Leading international and Swiss experts will share their current practices, latest developments and challenges across the analytical process.
