PREVENTIVE MAINTENANCE
Maintenance checklist
Daily / each use
- Check reagent levels and waste
- Check blank response is low and stable
- Check for leaks or error messages
Weekly / monthly
- Replace acid and oxidiser reagents as required
- Inspect sample tubing and autosampler needle
- Check carrier gas flow and pressure (combustion models)
Six-monthly
- Replace the UV lamp or combustion catalyst as advised by the supplier
- Replace pump tubing and membranes
- Calibration with standards
Annual
- Preventive maintenance by a trained engineer
- Requalification (OQ) as per SOP
- Software and audit-trail review
SAFETY
Safety precautions
Before you work on the TOC analyser
- Acid and persulphate reagents are corrosive or oxidising: wear gloves and eye protection.
- UV lamps emit harmful radiation: do not look at the lamp with the cover removed.
- Combustion models have hot zones; let them cool before maintenance.
- Handle compressed gas cylinders according to site safety rules.
