ABSTRACT

The use of gas diffusion for ammonia colorimetric testing has become more popular over the last several years as an alternative to distillation. We will discuss the principle behind gas diffusion and how gas diffusion compares to distillation. We will also discuss EPA acceptance for the ammonia by gas diffusion method, maintenance and care for the system, what types of samples the method is suitable for, as well as the ammonia colorimetric testing following gas diffusion.
