Description

General description: SRM 2141_certSRM 2141_SDS
Application: Urea Standard reference material (SRM) is certified for calibrating and standardizing microchemical procedures aimed at determining nitrogen in organic matter. Additionally, it serves as a tool for standardizing techniques for nitrogen determination, when carbon and hydrogen are simultaneously analyzed.
Features and Benefits: Available with a certificate documentingnitrogen value determined through a modification of the AOAC micro-Kjeldahlmethod.
Other Notes: Example analytes are listed below as a reference. Please download a current certificate at nist.gov/SRM for current analytes and certified values.Nitrogen (N)See certificate for values and more details at nist.gov/SRM.
