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.
在不同氨浓度下比较了伯塞洛特法和奈斯勒法测定氨的精密度。根据预期氨浓度范围，就最适合使用的技术提出了建议。研究了微扩散分离对氨测定精密度的影响，同时评估了一种水溶性封盖密封剂以及一种模型胺污染物的影响。
