Abstract
The article discusses the features of using the mass balance (MB) method widely used in the Russian Federation to determine the purity of a selected group of organic components – such substances, and the MB model was adapted for substances suitable for separation or purification by distillation. Then an optimized algorithm for determining the purity of these components was developed. The operability and efficiency of the proposed approach is demonstrated on the example of benzene. The approach included the MB model and research algorithm. It has been successfully implemented on the State Primary Standard GET 208; the units of the mass fraction of the main component in benzene, toluene, n-heptane, isooctane, n-dodecane, n-hexadecane, propane‑1, propane‑2, n-octanol are reproduced using the algorithm. Certified pure substances were used to create certified reference materials (CRMs) for the composition of the corresponding organic compounds. The proposed approach can be applied in the future for the rapid expansion of the list of GSOs for the composition of organic components
