The standard sample of the propanol-2 solution composition is intended for:
- Certification and error control of measurement methods
for propanol-2 content in biological objects, environmental objects and technical products;
- For verification, calibration and calibration of chromatographs and other, including specialized, measuring instruments (SI) designed to determine propanol-2 in biological objects, environmental objects and technical products, as well as for monitoring the metrological characteristics of SI during their tests, including for type approval purposes.
Technical specifications:
- The mass concentration of propanol-2 is 4.00 g/dm3;
- The limits of the relative error of the certified value of CO - ?, at P = 0.95, are ± 1.0 %;
- The standard sample is an aqueous solution of propanol-2 (propane-2-ol), with a mass fraction of the main component (A) of at least 99.7%.
The shelf life of a copy of CO is 1 year.
Basic equipment:
- A glass ampoule containing 3 ml of GSO solution - 1 pc.;
