Description
This low alloy steel 4620 certified reference material is a nickel-molybdenum alloy steel used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, OES). This material was prepared following ISO Guides 30, 31, and 35, with certified values established through interlaboratory testing, giving you traceable, defensible composition data for calibration checks, instrument verification, and quality control.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
