About this event
Join SEAL Analytical’s chemists for practical guidance on improving ammonia and Total Kjeldahl Nitrogen (TKN) colorimetric analysis. Whether you use continuous flow analyzers, discrete analyzers, or manual techniques, this session will help you understand the chemistry behind your methods, troubleshoot common challenges, and achieve more consistent results.
This webinar will cover:
- Method fundamentals: How Kjeldahl digestion and the Berthelot colorimetric reaction work together to measure TKN (and ammonia)
- Digestion best practices: Temperature control, acid-to-salt balance, catalysts, and sample reconstitution, including troubleshooting incomplete digestions
- Reagent preparation and storage: Including practical considerations for salicylate versus phenate and determining the best hypochlorite source for your analysis
- Interferences and method optimization: Managing challenging sample matrices, checking reaction pH, matching samples and standards, and using synthetic diluent to investigate analytical issues
We’ll conclude with a live Q&A, giving you the opportunity to bring your questions and discuss practical solutions with SEAL’s technical team.
