JEOL AminoTac JLC-500/V
JEOL · Model AminoTac JLC-500/V
Eluent pump Flow sensor feedback and phase-control pulse mixing type. Flow rate constancy under pressure.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
QC / calibration failure / poor peaks or results
HighSymptoms: Controls out of range, calibration fails, poor chromatographic peaks, baseline drift.
Root cause: Column / mobile-phase issue, detector lamp ageing, a pump / seal fault, or a reagent problem.
Pump pressure / flow instability
MediumSymptoms: Pressure spikes or drops, unstable flow, retention-time drift.
Root cause: Worn piston seals or check valves, a blocked frit, or air in the pump head.
Autosampler / injector fault
MediumSymptoms: Missed injections, poor injection precision, vial-detection errors.
Root cause: Rotor-seal wear, a syringe / metering fault, or needle mis-alignment.
Detector / flow-cell fault
MediumSymptoms: High noise, low signal, detector-error message.
Root cause: Lamp at end of life or a contaminated flow cell.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: QC / calibration failure or poor peaks
- Confirm the correct column, mobile phase, temperature and reagents.
- Check the detector lamp energy and replace it if low.
- Clean or replace the flow cell.
- Purge the system and let it equilibrate.
- Run a known standard to confirm performance.
Symptom: Pump pressure / flow instability
- Check the mobile-phase level, degassing and the inlet frit.
- Prime the pump and purge air from the head.
- Inspect the piston seals and check valves for wear.
- Leak-test the fittings from pump to column.
- Replace the seals / check valves as isolated.
