Description
Certified reference material for Alloy 20 (UNS N08020), intended for XRF and spark OES calibration, verification, and quality control.
The Alloy 20 CRM is designed for XRF and spark optical emission spectroscopy (OES) applications where accurate verification of nickel-iron-chromium austenitic alloys is required.
Alloy 20 is widely used in chemical processing, sulfuric acid service, and corrosion-resistant applications, where controlled additions of nickel, chromium, molybdenum, and copper are critical. This certified reference material supports reliable measurement of those key alloying elements, along with minor and trace constituents used to confirm Alloy 20 chemistry.
The CRM is supplied as a solid metallic disc, providing a stable and repeatable surface for XRF and OES analysis.

Frequently Asked Questions
What is this reference material used for?
This CRM is used for calibration, verification, and quality control of XRF and spark OES analyzers when analyzing Alloy 20.
Is this suitable for handheld XRF analyzers?
Yes. Nickel, chromium, copper, molybdenum, and iron in Alloy 20 are well suited for verification using 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 include light elements?
Yes. Elements such as carbon, nitrogen, hydrogen, and oxygen 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.
