Determination of TOC and DOC in Surface Water

This case study addresses the challenges of accurately measuring dissolved organic carbon (DOC) and total bound nitrogen (TNb) in carbonate-rich surface waters. It highlights the solution provided by the multi N/C series software and the NPOC plus method, ensuring high sample throughput and precise results while overcoming issues related to filter blank values and suspended solids. The study emphasizes the importance of surface water quality monitoring and compliance with DIN EN ISO 20236 standa
