Current analytical questions

- Elaboration of publications for the implementation of the analysis. Currently dealing with processing factors, sample preparation and safeguarding measures
- Handling and revision of standardized methods / norms, e.g. for iodine
- Practical reports on analytical topics from members, such as determination of vanadium, experience reports on large-scale equipment
