Sampler
Let’s take a look at what’s going on with CheckPoint’s mechanism:
UPW flow’s into the sampler. Now it’s important to know that the flow of water coming into the sampler needs to be at least 60 ml/min with a minimum pressure of 15 psig, not to exceed 100 psig. Within the sampler there are two key features that I would like to highlight. The first one is the flow disc- the flow disc regulates flow through the sample stream at `60 ml’s/min. The second part that is critical is the check valve. The check valve helps keep a constant pressure on the system of 6 psig.
The sample water passes Conductivity Cell 1 to determine the baseline conductivity.
After passing by Cell 1, the sample enters the UV Reactor. At this point; Partial Oxidation occurs; converting the organics present in the sample to organic acids.
The ionic organic acids then pass Conductivity Cell 2 where the difference in conductivity is measured.
No Membrane, No Reagents, No Di-Loop.
Partial oxidation
Oxidation forms organic acids.
Oxidation dependant on amount of dissolved oxygen in the sample.
Different organics form different organic acids.
Empirically derived model.
