Description
Certified reference material for 2507 Super Duplex Stainless Steel (UNS S32750), intended for XRF and spark OES calibration, verification, and quality control.
The 2507 Super Duplex Stainless Steel CRM is designed specifically for XRF and spark optical emission spectroscopy (OES) applications where accurate verification of high-alloy stainless steels is required.
This material supports reliable measurement of key alloying elements such as chromium, nickel, molybdenum, manganese, and supporting trace elements that define super duplex 2507 chemistry. It is well suited for routine analyzer checks, method validation, and ongoing QA/QC programs in both handheld and laboratory environments.
The CRM is supplied as a solid metallic disc, providing a stable, repeatable surface for XRF and OES testing.

Frequently Asked Questions
What is this certified reference material used for?
This CRM is used for calibration, verification, and quality control of XRF and spark OES analyzers when analyzing 2507 super duplex stainless steel.
Is this suitable for handheld XRF analyzers?
Yes. The major alloying elements in 2507—such as chromium, nickel, molybdenum, and manganese—are well suited for verification with SDD-based handheld XRF systems.
Can this be used for spark OES?
Yes. The solid disc form and certified homogeneity make it suitable for spark OES calibration and performance checks.
Does this material include carbon and nitrogen values?
Yes. Carbon and nitrogen are included to represent full alloy chemistry, but they are not measurable by handheld XRF and are primarily relevant for OES users.
Is this supplied as chips or solid form?
This CRM is supplied only as a solid disc for repeatable XRF and OES analysis.
