Features and Benefits: • The certified value of the SRM was determined by calculating the mass fraction values of Potassium, which is obtained through two methods:
  1. Gravimetric preparation using Potassium Chloride
    •  Inductively coupled plasma optical emission spectrometry (ICP-OES).
• The certified value is metrologically traceable to the SI unit of mass fraction, expressed as micrograms per gram.
• The NIST certificate is provided with expiration certificate, use, storage, handling, and maintenance instructions.
General description: Each unit of SRM 3141A contains five sealed borosilicate glass ampoules, each containing 10 mL of an acidified aqueous solution. This solution is gravimetrically prepared to contain a known mass fraction of potassium. and comprises of nitric acid at an approximate volume fraction of 1 %.
