'sample-preparation' 검색 결과

Measurement techniques for identifying composition, microstructure, and properties of engineering materials — optical and electron microscopy, x-ray diffraction, EDS and WDS spectroscopy, thermal analysis, mechanical testing, and fractography. Covers when to use which technique, sample-preparation pitfalls, and how to build a characterization plan that answers a specific engineering question rather than accumulating data for its own sake.

Plan a comprehensive spectroscopic analysis campaign by defining the analytical question, assessing sample characteristics, selecting appropriate techniques using a decision matrix, planning sample preparation for each technique, sequencing analyses from non-destructive to destructive, and defining success criteria with a cross-validation strategy.

Use this skill when an external audit, attestation examination or assessment is coming and the team wants populations and evidence ready for the samples the auditor will pull, or asks "prepare for audit sampling", "what samples will the auditor ask for", "get our populations ready", "the auditor wants a list of all changes in the period", "evidence for the leavers sample", "Type II sample prep" or "how do we prove completeness of the population". Lists the populations an auditor is likely to sample, builds each from the system of record with the query that produced it, checks completeness and the evidence behind a dry-run sample, and writes a readiness file per population plus a list of gaps to fix before fieldwork.
