In 2026 major changes will take place in the regulations for analyzing wastewater in the Benelux. After decades of analyzing these samples on Chemical Oxygen Demand (COD/CZV) and Kjehahl (TKN), these environmental pollutting analysis are replaced by the environmentally friendly TOC/TNb analysis. In Belgium the new norm is WAC/III/D/050 and in The Netherlands NEN-ISO-20236. The Shimadzu TOC-L and TNM-L meet the requirements needed for these norms including the cellulose test mentioned in these norms.
