Abbott ARCHITECT i4000SR
Abbott · Model ARCHITECT i4000SR
Users benefit from the seamless transfer from system to system. Equivalent results across all ARCHITECT i Systems Identical technology, reagents and assay protocols Identical software that is intuitive to operate Universal ARCHITECT sample carrier Users benefit from a unique approach to consolidation. No clinically significant sample tube to tube carryover (less than 0.1 ppm) Robotic Sample Handler (RSH) eliminates bottlenecks and prioritizes urgent requests Immediate STAT processing for fast and consistent turnaround time Up to 50 refrigerated reagent positions Continuous sample access loading of up to 285 samples via priority (35) and routine (250) areas Throughput of up to 400 immunoassay tests per hour Users benefit from the latest in immunoassay technology. CHEMIFLEX technology delivers flexible assay protocols with superior detection and extended linear ranges Up to 50 color-coded, refrigerated onboard reagent positions and flexible kit sizes of 100 or 500 tests provide high reagent test capacity of up to 25,000 tests to optimize walkaway time Liquid level sensing combined with pressure differential technology for enhanced bubble and clot detection ensures accurate sampling.
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.
QC / calibration failure on an assay
HighSymptoms: Controls out of range, calibration fails, flagged results on one or more assays.
Root cause: Reagent pack issue, a probe / dispense fault, incubation-temperature drift, or a detector / optics fault.
Sample / reagent probe or pipettor fault
MediumSymptoms: Short aspiration, no dispense, clot / level-sense errors, carryover.
Root cause: Clogged or bent probe, a syringe / pump fault, or a level-sense fault.
Wash / aspiration station fault
MediumSymptoms: High background / noise, poor precision, elevated blanks.
Root cause: Blocked wash-station nozzles or a wash-pump / vacuum fault.
Incubator temperature fault
MediumSymptoms: Assay drift or bias, incubation-temperature alarm.
Root cause: Incubator heater or temperature-sensor fault.
Detector / luminometer / photometer fault
MediumSymptoms: Low signal, high CV, detector-error message.
Root cause: PMT / detector ageing or an optics fault.

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: QC or calibration failure
- Run fresh controls and recalibrate the affected assay.
- Confirm the reagent pack is in date, mixed and correctly loaded.
- Clean the probes and wash stations.
- Check the incubator temperature against a reference.
- Escalate a detector / optics fault to the OEM.
Symptom: Probe or pipettor fault
- Inspect the probe for a bend or clog and clear it.
- Run the fluidics prime.
- Check the syringe / pump and tubing for leaks or air.
- Verify level sensing and probe position.
- Replace the probe or syringe as found and re-run QC.
