Laboratory Instrument Data Integration Requires Context Preservation
Holding
Instrument integration is reliable only when measurements remain connected to method, sample, calibration, and operator context.
Issue
Connecting an instrument to a LIMS is not the same as preserving scientific meaning. A numeric result without method version, units, sample identity, or calibration state is incomplete evidence.
Analysis
The practical issue is context loss at the integration boundary. A parser may move values successfully while dropping instrument settings, quality flags, run identifiers, or the relationship between a result and its source file.
Resolution
The relevant control is a canonical data model with explicit provenance. Each imported result should retain source instrument, method, units, calibration reference, sample, operator or service identity, timestamp, and validation status. Failed imports should enter a visible exception queue.
Evidence Package
The evidence should include interface specifications, mapping tests, rejected-message logs, source-file references, reconciliation reports, and change approvals for parsers and mappings.
Conclusion
An instrument interface should be evaluated by the context it preserves, not merely by the records it transfers.
