Quite often, in metallurgy and mechanical engineering, spectral analysis is used to determine the composition of an object. A spectral analysis laboratory assistant can correctly apply this method of study.

Description of the profession

The spectral analysis laboratory assistant not only examines various samples, but also evaluates them with the help of special instruments. He also needs to have an idea of ​​​​how the equipment used functions, what are its features, how to build its work correctly.

The duties of a specialist include quality control of samples taken for analysis, and preparatory work with solutions and equipment.

In order to work as a laboratory assistant, it is necessary to pass a medical commission, briefings, as well as an internship, which can last about 14 days. After completion of the internship, it will be necessary to pass certification, confirming the required level of knowledge. In the future, such an audit will be carried out annually.

The spectral analysis laboratory assistant is informed about the negative factors that he may be exposed to during the performance of his labor obligations. Therefore, he should not neglect safety precautions and special equipment: an apron, gloves, glasses. Also, laboratory assistants are taught to provide first aid in case of emergency.

Before starting work, the laboratory assistant must inspect his working space, check the operability of all devices and the condition of the protective equipment. If any of this does not meet quality standards, has malfunctions and defects, you must immediately contact the higher management with the problem. It is strictly forbidden to start work with incorrectly working equipment.

At the end of the working day, the spectral analysis laboratory assistant must reset his workplace, check the entire inventory, complete the reporting. If the employee works on a shift schedule, he needs to transfer all the data to a colleague.

The spectral analysis laboratory assistant has extensive employment options. For example, he can work in public or private laboratories, conduct research for the metallurgical field or astrophysics.
