애플리케이션

The SRM is intended for chromatographic instrumentation calibration, used in the determination of hopanes and steranes.

특징 및 장점

• The certified value of the SRM was determined by calculating the mass fraction values of three hopanes and four steranes which is obtained through two methods:

1. Gravimetric preparation of the solution.
2. The analytical results determined using gas chromatography.

• 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, storage, handling, use,and maintenance instructions.
