The calibration due date is visible, but an auditor may examine the complete evidence that a MiniCapt® Mobile or MiniCapt® Pro remained suitable throughout its use period. The record set should connect model and serial number, assigned location, flow configuration, sampling head, cleaning status, calibration, maintenance, deviations and the data generated by the instrument.

For mobile units used across several rooms, location traceability and cleaning status are especially important. The organization should be able to show when the sampler moved, which approved recipe was used, how accessories were controlled and how the device was released after service or decontamination.

Before shipment, record the model, serial number, nominal flow, firmware where applicable, power accessories, sampling head and communication components. Review flow alarms, interrupted samples, unusual sample duration, repeated runs and any trend that could indicate deterioration. Include clear symptoms in the service request rather than sending the instrument with only a generic calibration instruction.

Inspect the impactor head, holes, threads, seals and contact surfaces for blockage, damage, corrosion or inadequate cleaning. Do not use sharp objects that may change hole geometry. Decontaminate the equipment using an approved, material-compatible procedure and confirm that no media, liquid, chemical or biological hazard remains before packing.

After service, QA should review both as-found and as-left information. As-found describes the condition before adjustment or repair and may trigger an assessment of data collected since the last known acceptable state. As-left confirms the condition after service and should match the intended use range before release.

If as-found results are unacceptable, the response should not stop at filing the new certificate. The site should assess the failure type, magnitude, potentially affected interval, associated batches and environmental data, product risk and the need for investigation or CAPA. Parts replacement or functional changes may require change-control review.

Plan service around production and transport time. Identify monitoring points that will be unavailable, prepare a calibrated replacement if appropriate and document equivalence for model, flow, sampling head, media and workflow. After return, complete receiving inspection, document review, self-test or functional checks and quality release before the instrument is used again.

SAO NAM Life Sciences is the specialized Life Sciences representative of Particle Measuring Systems in Vietnam and the exclusive distributor of MiniCapt® and BioCapt® solutions in the Vietnamese market under the current authorization scope. Lifecycle support may include service planning, inspection, calibration, preventive maintenance, repair, accessories, documentation review and coordination with PMS specialists, depending on instrument condition and service agreement.

The service program should also define responsibilities at every handoff. Operations identifies the production window and affected monitoring points; microbiology secures media and sampling accessories; engineering prepares the instrument and shipping condition; QA reviews impact, service evidence and release. The service request should clearly separate routine calibration from a reported functional problem so that troubleshooting evidence is not lost. On return, compare serial numbers and accessories, inspect transport condition, review parts replaced and confirm that approved recipes and communication settings remain appropriate. If a replacement sampler was used during the outage, reconcile its data and location records before closing the temporary change. These controls create a continuous evidence trail from removal through return to service and reduce last-minute questions during an audit.
