Certified reference materials - Coals and Cokes

Get to know our ISO 9001 coal and coke certified reference materials

Elemental Microanalysis has a large range of ISO 9001 produced coal and coke certified reference materials:


Each group offers a different set of analysis values, a simplified summary is detailed above. 

The coal and coke CRMs are supplied as finely ground powders, tested to ASTM specifications and are metrologically traceable through calibration to a primary standard e.g. NIST SRM 2682c (some exceptions). This information is provided on the certificate of analysis as well as expanded uncertainty for the values certified.

The full range of reference materials along with their current certified values can be downloaded from our website. These CRMs are predominantly secondary measurement standards (ISO guide 30).

Available to order from our ISO 9001 factory online, by email, telephone or fax. Elemental Microanalysis offers extensive knowledge of analysis, over 40 years of experience and a worldwide reputation for excellence.
