EXPRESS NALYSIS OF UNKNOWN ORGANIC SUBSTANCES Nelli Hovhannisyan
Conducting chemical experiments and analyzing them take up most of the time from all the work of scientists. Any chemist can mix and dissolve reagents, but for some research and experiments, you need to repeat the same manipulations hundreds of times while maintaining the accuracy of the proportions of the reagents. Besides, a considerable amount of effort is spent combining reagents with each other and fixing the results obtained. All these processes are similar in that they require repeating the same actions with a slight difference in the variables.
Of course, modern instrumental methods of chemical analysis come to the rescue. They are highly accurate, based on the latest principles of contemporary science, and often require modern equipment and highly specialized service personnel.
The work of the laboratory staff is based on the analysis of the received samples of raw materials and products. At the same time, working in a chemical laboratory can be dangerous, and specific standards and requirements for equipment and reagent storage have been developed to protect the personnel.
Therefore, to achieve the best results, it is necessary to make substantial financial and labour intensive investments in chemical laboratories. This is fully justified in a number of forensic and innovative research laboratories, where each study is unique and often has several legal implications.
However, a large number of chemical laboratories carry out routine work daily. A fully equipped chemical laboratory allows you to study the properties of individual substances and materials, to observe the course of the interaction of reagents. The main goal of the employees of chemical laboratories is to create and implement express methods for the analysis of samples, which allow for quality control in the "field" conditions. Work is constantly underway to speed up the preparation of samples for
research, and screening methods of analysis are being introduced. These laboratories
need daily rapid tests that can be performed quickly and inexpensively. Using relatively
inexpensive chemical reagents, the simplest physicochemical, color, and other tests
presented in the article, the laboratory will quickly and efficiently complete its daily task
while avoiding expensive equipment.
We hope that this work will be helpful, especially for environmental and chemical
laboratories with limited resources and factory and various industrial laboratories,
because as a result, both material resources and, most importantly, time are saved.
