For an accredited laboratory, the LIMS is part of the evidence. When an assessor asks "who changed this result, and when?", the answer has to be in the system — not in someone's memory. OnLIMS is built so that data integrity, traceability and auditability are the default behavior, not a configuration you hope was switched on.
How OnLIMS maps to ISO/IEC 17025:2017
ISO 17025 accredits laboratories, not software. What your LIMS can do is make the relevant requirements straightforward to meet and to demonstrate:
| Requirement (theme) | OnLIMS capability |
|---|---|
| 7.5 Technical records | OnWSH worksheet templates capture each method's columns, formulas and QC parameters; raw instrument output is captured automatically. |
| 7.11 Control of data & information management | Microsoft SQL Server backend over ODBC, role-based access, Active Directory integration, encrypted credentials and multi-database isolation. |
| 8.4 Control of records | State machine (Pending→Ready→Approved→Published), a password-sealed lock on publish, and a multi-level audit log storing original value, new value, user and timestamp. |
| 6.4 Equipment | Native instrument integration (serial RS232 and file parsers, 150+ instruments) keeps calibration data and raw outputs traceable to their source instrument. |
Controls that support accreditation
- State-machine workflow Pending → Ready → Approved → Published enforces review before release — so nothing reaches a client without sign-off.
- Locked, audited results Published records are locked under password control, and every later change is captured in the audit trail — so no result changes in silence, and the auditor sees it.
- Multi-level audit log System and raw-data auditing — so "who changed what, when" is answered by the system, not by memory.
- Chain of custody Barcode traceability from field collection to certificate — so every sample has a defensible history.
- Method control via templates Worksheet templates hold each method, editable only by authorized roles — so methods don't drift between analysts.
- Access control Role-based permissions with Active Directory — so each user sees and does only what their role allows.
Built for remote mine sites
OnLIMS uses a zero-install model: executables and libraries run from a centralized network share, with a direct ODBC connection to SQL Server. That makes it practical where it matters — remote, low-bandwidth sites and virtualized environments (Citrix, RDS) — while keeping every workstation consistent and easy to patch from one place. Multi-database support lets test, development and per-client environments coexist cleanly.
Beyond readiness: OnQMS, the accreditation evidence module
OnLIMS gives the laboratory the data-integrity controls; OnQMS builds the accreditation evidence on top of them: ISO/IEC 17025 clause-by-clause coverage with drill-down to the actual records, proficiency-testing control charts (z-score, ISO 13528), competence and calibration records, impartiality and internal audits — with your accreditation body's guidelines cited by version, an optional local AI assistant that answers citing clauses, and a fully bilingual EN/ES interface.

Frequently asked questions
Does OnLIMS include an accreditation evidence module?
Yes — OnQMS maps the laboratory's real records to ISO/IEC 17025 clause by clause, with PT control charts, competence and calibration records, and country packs citing the local accreditor's guidelines by version.
Is OnLIMS certified to ISO 17025?
ISO 17025 accredits laboratories, not software. OnLIMS provides the data integrity, traceability and audit controls a laboratory needs to support and maintain its accreditation.
How does OnLIMS prevent results from being altered after approval?
Samples and worksheets follow a strict state machine. Once published, records are locked under password control, and any later change is recorded in dedicated audit tables.
Does OnLIMS keep an audit trail of data changes?
Yes — a multi-level log covering system events and raw-data changes (original value, new value, user and timestamp).
Can OnLIMS run at a remote mine site with limited bandwidth?
Yes. Its zero-install model runs from a network share with a direct ODBC connection, and it suits virtualized environments such as Citrix or RDS.
Which database does OnLIMS use?
Microsoft SQL Server, with most integrity logic handled server-side via stored procedures and views, and access governed by roles and Active Directory.
