Question

Read the following technical passage regarding shipboard life-support systems:

During scheduled maintenance of shipboard electrolytic oxygen generators (EOG), technicians must monitor deionized cell feedwater conductivity. The system requires feedwater with an electrical conductivity strictly below 2.0 microsiemens per centimeter ($2.0\text{ }\mu\text{S/cm}$) to prevent catalytic poisoning of the platinum-coated titanium anode plates. If the primary demineralizer bed effluent registers between $2.0$ and $5.0\text{ }\mu\text{S/cm}$, flow must be diverted through a secondary polishing canister before reaching the electrolysis cell. Conductivity readings exceeding $5.0\text{ }\mu\text{S/cm}$ necessitate immediate system shutdown and replacement of all resin cartridges.

Statement: According to the passage, when effluent conductivity from the primary demineralizer bed registers between $2.0$ and $5.0\text{ }\mu\text{S/cm}$, technicians must divert the fluid through a secondary polishing canister prior to it entering the electrolysis cell.
