Description
This 41L50 leaded steel reference material is a high-lead chromium-molybdenum steel used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, OES). This material provides a known composition for confirming your instrument's grade identification accuracy, supporting laboratories and field operations performing calibration, quality control, and materials testing — particularly for high-lead-content grades where standard verification samples can fall short.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
