Application

Obsidian rock standard reference material (SRM) is intended for assessing the precision of both analytical methods and instruments employed in analyzing geological materials.

Features and Benefits

  • Available with a certificate documenting NIST-certified values of constituents in the obsidian rock, these values were determined through either a definitive method, reference method, or two or more analytical methods.
  • Information values of the constituents are determined by single or non-reference method.
