Abstract
The precision of the Berthelot and Nessler methods of ammonia determination are compared at various ammonia concentrations. Recommendations are made regarding the most appropriate technique to use, dependent on the range of ammonia concentration expected. The effect of microdiffusion separation on the precision of ammonia determination is studied, together with an evaluation of a water soluble lid sealant and of the effect of a model amine contaminant.Entities:
