Key Points

To establish a direct Nesslerization micro-Kjeldahl procedure and modify the Nessler-Folin reagent for streamlined ammonia and nitrogen quantification.
Formulated a modified Nessler-Folin reagent optimized for direct colorimetric ammonia detection.
Developed a micro-Kjeldahl digestion protocol capable of direct Nesslerization without requiring preliminary distillation.
Eliminated the requirement for steam distillation in micro-scale Kjeldahl determinations through direct Nesslerization.
Achieved stable and reproducible color development for quantitative ammonia assessment using the modified reagent formulation.
