High-Purity Standards offers a broad range of ISO 17034:2016 certified single and multi-component ICP-OES standards. The accuracy of all standards is verified against NIST Spectrometric Standard Solutions where available (otherwise against an ISO 17034 second source Certified Reference Material).
Single-Element Standards We offer single-component standards in the broadest range of matrices available. You can locate the element alphabetically by name, or search by part number. The part number is based upon concentration (100, 1,000, or 10,000 (referred to as 10M); the last 2 digits of the associated NIST SRM 3100 series; and the matrix: HNO3 (-1), HCl (-2), HNO3 + HF (-3), H2O (-4), other options (-5 and up). Thus a 1,000 µg/mL solution of aluminum in nitric acid is 10001-1; a 10,000 µg/mL solution of tin in nitric and hydrofluoric acids is 10M61-3; and a 100 µg/mL solution of gold in hydrochloric acid is 100-21-2. The aluminum solution is traceable to the NIST SRM 3101, the tin to NIST SRM 3161, and the gold to NIST SRM 3121.
