Laboratory Analyzer Troubleshooting – Master Guide
Central decision logic for diagnosing common laboratory analyzer problems.
Signal Related Problems
- No signal → Detector / lamp failure
- Noise → Electrical grounding issue
- Drift → Temperature instability
Calibration Issues
- Low R² → Standard preparation error
- Non-linearity → Detector saturation
- Poor repeatability → Sample handling issue
Flow Based Systems
- Pressure fluctuation → Pump seal issue
- Leak → Fitting / ferrule damage
- Blockage → Column contamination
