Abstract
The present article studies the metrological characteristics of AMV-1006M NMR analyzers obtained during their calibration to determine the mass fraction of oleic acid in sunflower oil. Calibration is of great importance for obtaining repeatable and reproducible measurements of the quality indicators of agricultural raw materials using measuring instruments. Calibration can be carried out in different ways. In this case, the calibration procedure is performed using sunflower seeds and specially developed imitator reference materials (RMs) for the mass fraction of oleic acid in seed oil. The developed imitator RMs are characterized by high long-term stability of their physicochemical parameters and do not require special storage and operating conditions. The obtained data confirm the feasibility of using these imitator RMs for calibration purposes. In the calibration of analyzers, the random error limits of measurement results when using natural seeds exceeded those obtained with the use of imitator RMs by a factor of 3. Furthermore, the study of the temperature effect on calibration results indicates that the standard deviation of measurement results does not exceed 0.8 abs% for the imitator RMs, whereas the use of natural seeds yields 2.5 abs%.
