Certificate of Analysis — ISO 6141
Issue a certificate against the standard your customers audit you on, with a registry of every certificate issued and the payload preserved as it was signed. Not a Word template with the numbers pasted in.
Fluids capability
Quality & Compliance
This is the part of Fluids that surprises people. It is not a quality checkbox on a dispatch screen — it is a laboratory information system with certificates, uncertainty calculation, calibration control, sampling plans and an audit trail, sitting inside the same system as your orders and your invoices.
The test it has to pass
A customer's quality department rejects your certificate. An auditor asks which instrument produced a result from eighteen months ago and whether it was in calibration that day. A specification changes and you need to know which lots were released under the old one. If your answer to any of those is a folder and a phone call, this is the module that changes it.
Standards
Implemented to, not merely mentioned
These are the frameworks the calculations and record formats follow. Certification is yours to hold — this gives your audit something to stand on.

Capabilities
What the lab module actually does
Measurement Uncertainty — ISO 6142
Expanded uncertainty at k=2 calculated per component of the mixture, attached to the certificate. The number your customer's quality department will ask for, computed rather than quoted.
Analyzer Register — ISO/IEC 17025
Every analyzer registered with its calibration history and validity window. A result recorded on an out-of-calibration instrument is caught, and due dates raise alerts before they expire.
Electronic Signature and Audit
Analyst signs, reviewer countersigns. Every edit to a result after entry is written to a separate audit table that the application cannot rewrite. Test methods are versioned, so you know which SOP a two-year-old result was produced under.
SPC and Trend
Control charts and stability trending over your own results, so drift is visible as drift rather than as a run of individually acceptable numbers.
AQL Sampling — ISO 2859-1
39 sampling plans seeded — inspection level II, normal severity, single sampling, AQL 1.0, 2.5 and 4.0, code letters A through N — applied to production lots with accept and reject numbers computed for the lot size. Replaceable with your own QA standard.
NCR and CAPA
Non-conformances raised manually or automatically from receiving and inspection, with root cause, disposition, corrective action and closure. They feed the vendor scorecard, so a supplier's quality shows up in their next evaluation.
Quality Economics
Cost of quality, first-pass yield and defect Pareto — the numbers that turn a quality argument into a financial one.
Test record
Six detail sets behind every gas quality test
- Components
- Declared and measured concentration per component of the mixture, with tolerance.
- Impurities
- Impurity limits and measured values, recorded against the specification the customer bought.
- Physical
- Physical property measurements captured alongside the compositional analysis.
- Stability
- Stability observations supporting shelf life and re-test intervals.
- Compliance
- Explicit pass or fail against the applicable specification, not left to interpretation.
- Instruments used
- Which analyzers produced the result, so calibration validity can be checked against the test date.
Consequence
Quality results change what happens next
A result that only lands in a report is a filing exercise. In Fluids a result moves the operation.
A failed test raises work, not an email
A failed quality check automatically raises a rework production job and creates a child re-test that carries a reference to its parent, so the chain from failure to resolution is a record rather than a memory.
Receiving inspection auto-raises NCRs
Goods received that fail inspection raise a non-conformance without anyone remembering to. The vendor's scorecard reflects it at the next period close.
Final inspection gates dispatch
The pre-dispatch inspection captures photographic evidence and annotated defects, and its result drives the dispatch-readiness board — ready, partial or blocked.
Instrument data can come straight from the instrument
Results can be batch-imported from analyzer output with a review-and-apply step, tagged by source. The endpoint already accepts PLC and SCADA sourced data for when you connect the floor.
