The TL-2800 ammonia analyzer from Timberline Instruments uses continuous-flow gas diffusion/conductivity cell analysis to determine ammonia levels. The method provides results unaffected by turbidity or color and does not require distillation before analysis. The system introduces the sample via peristaltic pump, reducing filtration, repairs and maintenance. Passing the sample/caustic mixture through an optional zinc reduction cartridge reduces nitrate and nitrite ions to ammonium, allowing measurement of total inorganic nitrogen. The software automates the instrument and sampling system, and the graphical user interface is easy to learn and implement. 303/440-8779;
