Does a traceable standard remove the need to assess real samples?
No. It supports a defined performance check. Sample-specific preparation, optical assumptions and method suitability still require evaluation.
Distinguish instrument verification from application-method evaluation. A suitable standard can check performance under specified conditions, while a real sample may introduce different dispersion or sampling questions. Retain the material certificate, handling conditions and acceptance basis with the verification record.
Planning particle analysis quality
Define what is being compared before collecting repeated measurements. Sampling, preparation, instrument performance and result evaluation contribute different sources of variation. Keep the measurement definition and comparison conditions with the result so that a change in the material can be distinguished from a change in the procedure.

Questions before selecting a configuration
How can Glen Mills help with this application?
Share reference selection, handling record, decision rule when you contact Glen Mills for further information or a quote. This helps focus the discussion on the preparation and evaluation described here.
How should a measurement result be assessed?
Use the size definition, distribution basis and acceptance criteria required by your measurement method. Discuss particle measurement with Glen Mills when a representative trial is needed to evaluate the configuration.
