Application

SRM921A Cortisol standard reference material (SRM) is intended for use in the calibration and standardization of clinical measurement laboratory procedures, used to quantify levels of cortisol.

Features and Benefits

  • Available with a certificate documenting NIST-certified mass fraction value of cortisol.
  • Certified value was determined using a quantitative 1H-nuclear magnetic resonance spectroscopy (1H-qNMR) primary ratio measurement procedure.  
  • Certified values are metrologically traceable to the International System of Units (SI) and SI-derived unit of mass fraction. 
  • The NIST certificate is provided with storage, source, preparation, analysis details and use instructions.

General description

Each unit of SRM 921A contains 1 g of high-purity crystalline cortisol.
