Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Development of a Virtual Training System for Working With a Gas Chromatograph in the Unreal Engine Software Application A.M. BESSARABOV, D.A. MOSKALENKO, E.R. VISHNIKINA, V.E. TROKHIN 3D models of the Chromatec-Crystal 5000.2 gas chromatograph and the auxiliary equipment required for its operation were developed. The models were deployed in the Unreal Engine environment in a virtual simulator of a chromatographic analysis laboratory. A training scenario for user interaction with the objects was implemented, consisting of three stages: preparing the equipment for analysis; introducing a sample of the liquid to be analyzed into the chromatograph detector; and computer analysis of the results using the Chromatec Analyst 3.0 software. Keywords: virtual modeling, training system, Blender, Unreal Engine, analytical laboratory, gas chromatography. DOI: 10.25791/pribor.1.2026.1644 Pp. 32-41.
