THE IMPACT OF MICROLAB EXPERIMENTS ON THE DEVELOPMENT OF PROFESSIONAL COMPETENCIES IN ANALYTICAL CHEMISTRY STUDENTS

The article provides a comprehensive analysis of the impact of microlaboratory experiments on the formation of professional competencies of students in analytical chemistry in the context of laboratory modernization and increased requirements for the accuracy of analytical measurements.The relevance of the transition to micro-methods is justified by the need to increase the sensitivity and reproducibility of results, rationalize reagent costs, reduce environmental impact, and ensure safe working conditions.The results of modern domestic and foreign studies confirming the effectiveness of miniaturized experimental approaches in the professional training of future chemists, in particular their impact on the development of accuracy, responsibility, skills in working with small volumes, digital recording and data interpretation skills, are summarized.It has been demonstrated that the use of microdevices, portable spectrophotometers, microcuvettes, chip sensor systems, and microplates enables students to master hightech analysis methods, promotes the development of analytical and critical thinking, and expands the possibilities for individual and group work in laboratory courses.It is emphasized that micro-laboratory technologies create conditions for intensifying the educational process, allow for a series of parallel experiments to be carried out in a short period of time, increase learning motivation, and provide flexibility in planning laboratory modules.Special attention is paid to chemical safety aspects, including waste reduction, minimization of the risk of contact with toxic substances, and the development of environmentally responsible behavior.Criteria for evaluating the effectiveness of micro-laboratory training have been identified, including measurement accuracy and reproducibility, the development of professional skills, and the dynamics of motivational and behavioral indicators.It has been concluded that micro-methods have significant potential for improving the quality of specialist training, ensuring compliance with modern technological, safety, and Журнал «Перспективи та інновації науки» № 12(58) 2025 118 environmental standards, and that the implementation of such approaches in higher chemical education is promising.
