The analyser had been running without attention since the annual service in January 2025.\n\n### Work carried out\n\nThe flow cell was removed, stripped and cleaned, and the pump tubing set replaced. The optical window was found to be lightly fouled on the inner face; it was cleaned rather than replaced, and should be inspected again at the next visit. The analyser was recalibrated against the two-point standards and left running on channel 2 for an hour before the site was handed back.
