Touch-screen monitor. Unique reagent Time Pacs. Three modes of aspiration: autosampler, open mode, and unique manual closed-tube sampling. Unique Unifluidics technology - reduced fluidics, no pinch valves, automated daily cleaning. Completely automated start-up Quality results - Results that are right the first time The ADVIA 2120i system uses gold-standard peroxidase staining for WBC differential testing. Fewer reruns. Lowest overall review rate. Faster turnaround time. Lowest linearity - 0.02-400k The system also offers state-of-the-art technology for RBC, reticulocyte, PLT and CSF testing. RBC. True RBC differential. Consistent morphology. Reduced manuals. Unique dual-hemoglobin measurement capability - eliminates interference from lipemia Automated Reticulocyte Analysis. Direct measurement, not calculated. Excellent in pediatric and dialysis populations PLT. Two dimensions - size and refractive index. Measures up to 60 fl. Includes large platelets in count. Excludes fragments and microcytic RBCs CSF. Results in <5 minutes. Linear to zero with three-part differential. Automated counting provides quality control for consistency.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Aperture / flow-cell blockage or partial obstruction
HighSymptoms: Flagged or implausible CBC counts, voteouts, clog alarms, poor precision.
Root cause: Debris or a clot partially blocking a counting aperture or the flow cell.
Sample probe / piercer / valve wear
MediumSymptoms: Short samples, aspiration errors, cap-piercing failures, carryover.
Root cause: Worn or bent sample probe / closed-vial piercer, or a worn shear / segment valve.
Reagent / lyse delivery fault
MediumSymptoms: WBC, HGB or diff results shifted, high background, reagent alarms.
Root cause: Reagent depleted or wrong lot, or a pinch-valve / tubing fault.
Optics / laser fault (diff)
MediumSymptoms: Diff scattergrams abnormal, missing populations, flow-cell or laser alarm.
Root cause: Contaminated or aged flow cell, or the laser / optics.
Vacuum / pressure out of range
MediumSymptoms: Multiple parameter errors, priming failures.
Root cause: Pump or regulator drift.

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.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
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: Clog / aperture / flow-cell alarm or flagged CBC counts
- Run the instrument's aperture / flow-cell clear (burn / back-flush) and flush cycles.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture bath / flow cell if clogs recur.
- Confirm precision on a replicate sample before releasing results.
Symptom: Short samples / aspiration errors / carryover
- Inspect the sample probe / closed-vial piercer for wear or a bend.
- Check the shear / segment valve and the tubing for leaks or wear.
- Verify vacuum and pressure against the service spec.
- Replace the probe / piercer, valve or tubing as found.
- Re-run controls and a carryover check.
Symptom: WBC / HGB / diff shifted / high background
- Confirm reagents and lyse are in date, primed and the correct lot.
- Check the pinch valves and tubing for wear or air.
- Run the fluidics prime and a background count.
- Recalibrate if the shift is confirmed against controls.
- Escalate an optics / laser fault if scattergrams are abnormal.
Symptom: Autoloader / transport jam
- Clear the jammed tube / rack and note where it hangs up.
- Inspect the autoloader belt, gripper and mixing station.
- Check the rack sensors.
- Cycle several racks.
- Replace the belt / gripper as found.
