Chromium (Cr) standard solution

Description

• General description: A unit of the SRM contains five 10 mL sealed borosilicate glass ampoules, consisting of an acidified aqueous solution. The solution is prepared gravimetrically to contain a known mass fraction of chromium and includes nitric acid at a mass fraction of approximately 15%. For more information, please refer to the SDS and COA.SRM 3112A_certSRM 3112A_SDS
• Application: Chromiumstandard solution is intended for use as aprimary calibration standard for the quantitative determination of chromium.
• Features and Benefits: NIST Certified Mass fraction value of Chromium is basedon gravimetric preparation using high-purity chromium metal and inductivelycoupled plasma optical emission spectrometry (ICP-OES).Expiration details, instructions for use, handling, andstorage are provided on the NIST certificate.
