THE INFORMATION-ANALYTICAL SYSTEM IN THE ASSESSMENT OF TECHNICAL AND OPERATIONAL PROPERTIES OF LIQUID MEDIUMS

The paper presents a prototype of information-analytical system Solvent-R created with Microsoft Access. Information-analytical system contains a database of physical, chemical, technical and exploitation, fire and explosion hazard, toxicological properties of individual and binary solvents. The system contains a set of production rules that regulate the trend of maximizing or minimizing solvent properties. Applying the generalized criteria or generalized functions, setting the boundary conditions, using the provided information and analysis system it is possible to find the optimum solvent composition for a given analytical problem. To determine the fire danger rating of solvents a new model of the objective function is proposed. Acetonitrile was adopted as a standard solvent, because acetonitrile is a base solvent in reversed-phase chromatography. Information and analysis system allows predicting the technical and exploitation characteristics of liquids that affect the quality of the instrumental chemical analysis, and the fire and explosion safety of individual and binary solvents used in the extraction sample preparation and liquid chromatography
