Direct Conductivity Method Sample Pump UV Reactor 2nd Conductivity Cell 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. 1st Conductivity Cell CheckPoint is a “continuous flow” UV/DC sensor
