Regular Inspection: The Reagent Tube should be regularly inspected for any signs of contamination, wear, or clogging. This involves checking for discoloration, residue build-up, or physical damage to the tube.
Signs of Wear: Replace the Reagent Tube if you notice a decline in analytical performance, such as inconsistent readings or if the tube shows physical signs of degradation (e.g., cracks, discoloration, or persistent contamination that cannot be cleaned).
