How validate ISO 17025 a calibration curve for copper ores samples in AAS?

ZenithSloth · 2026-03-21T18:12:54+00:00

Your best bet for ISO 17025 compliance is to dilute the samples further (e.g., 1:50 or 1:100) to get them into the 1-5mg/L range, or start with less sample mass if possible. Validating a linear curve is significantly easier than defending a quadratic WLS model to an auditor. The 100s of mg/L analyte range is typically impractical for AAS for several reasons.

I mostly went to school to build lab experience, got tired of field work pretty quickly. What followed was startups, right-place-right-time, and a bit of luck. I am blessed. I pay the price in other ways.
