General Information<br />
Principles of Operation<br />
The sample enters the <strong>Thermo</strong> <strong>Scientific</strong> Orion <strong>2110XP</strong> ammonia monitor<br />
and passes through the inlet valve, bypass/needle valve, inlet filter, pressure<br />
regulator, flow meter and into the restrictor tubing. The sample then passes<br />
through the flow cell manifold into a reagent bottle through a diffusion<br />
tubing assembly where pH adjustment takes place. The pH-adjusted<br />
sample then flows back through the manifold into the flow cell as air is<br />
introduced from the air pump to ensure proper mixing and fast response.<br />
The sample then flows into an atmospheric drain via the diverter valve.<br />
