NIST Urea is intended for use as a primary calibrant for the measurement procedures and validating methods used in clinical pathology laboratories to determine urea blood nitrogen.
其他說明
The NIST-certified mass fraction value for urea was determined using a mass balance approach for purity assessment, and the values are metrologically traceable to the SI derived unit for mass fraction, expressed as a percentage.
Maintenance and expiration of SRM certification, instructions for handling, storage, and use are provided on NIST certificate.
