Biochrom Biochrom 30
Biochrom · Model Biochrom 30
Convenience - Load and Go Post-column photometric detection of amino acids with no additional derivatization procedures. Flexibility - Integrated software enables automatic sample set-up, flexible sample analysis, networking and exporting of data. Versatility - A wide variety of sample types can be analysed using the available range of programs and columns. Compact - Bench top design requiring minimum lab space. Serviceability - Ergonomic design for ease of Maintenance.
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.
Pump pressure high or low / unstable
HighSymptoms: Buffer pump pressure outside the normal band, flow varies, retention times shift.
Root cause: Blocked in-line frit or column, worn pump piston seals, or air in the buffer line.
Baseline noise or drift
HighSymptoms: Noisy or drifting ninhydrin detector baseline, poor quantitation.
Root cause: Aged photometer lamp, air or bubbles in the ninhydrin reagent line, or a failing reagent pump.
Poor amino-acid separation
MediumSymptoms: Peaks merge or shift, resolution lost.
Root cause: Ion-exchange column aged, wrong buffer, or column-oven temperature off.
Reaction coil / heater fault
MediumSymptoms: Low colour yield, weak peaks across the board.
Root cause: Reaction-coil heater not reaching temperature.

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: Pump pressure abnormal
- Purge air from the buffer lines.
- Back-flush or replace the in-line frit.
- Check the column back-pressure against spec and replace an aged column.
- Replace the pump piston seals if pressure ripple is high.
- Re-run a standard and confirm stable pressure and retention times.
Symptom: Noisy or drifting baseline
- Prime the ninhydrin reagent line and remove bubbles.
- Replace the photometer lamp if energy is low.
- Check the reagent pump for leaks or worn seals.
- Confirm the reaction-coil temperature.
- Re-run a calibration standard.
