viitevalmiste
Viitevalmiste, in English often translated as reference preparation, is a well-characterized material used as a standard to calibrate analytical methods, validate procedures, and ensure traceability of results. It can take the form of a certified reference material, a standard solution, or other reference substances provided by producers or laboratories. Each lot is evaluated for identity and purity, and a certificate of analysis accompanies the material stating the assigned value and the associated measurement uncertainty.
Viitevalmiste serves to provide a known quantity of the target analyte, enabling accurate quantification through calibration
Production and characterization involve controlled manufacturing processes and validated analytical characterization. Key properties include chemical identity,
Types commonly include primary reference materials, certified reference materials, and in-house reference materials used for internal
Regulatory and quality frameworks govern the production and use of viitevalmiste, with guidance from pharmacopoeias and
