Laboratory assistant for chemical analysis of the basics of work. Chemical analysis laboratory assistant: responsibilities and job description. Reviews about the profession

There are many professions, the result of which is practically invisible to the layman. Scientists also belong to people of such labor. Moreover, it is they who largely contribute to technological progress, which, in turn, is changing the world in the most radical way. Whole groups of specialists are involved in this work, dealing with various aspects of the study of the surrounding world, properties and characteristics of objects. A significant contribution to the common cause of the development of human knowledge is also made by a laboratory assistant whose duties include carrying out research on various metals, ores, petroleum products, as well as other materials and substances. The data obtained is required to ensure control of the characteristics of products for their admission to further technological and production processes.

General information about the position

The main task of a laboratory assistant in this area is to obtain information of a chemical nature. In this case, the objects under study can be any. In addition to the already mentioned metals and petroleum products, a chemical analysis laboratory assistant can work with gases and vaporous components. The further use of the results may be different. The simplest example when a certain production needs to achieve specific properties of the product. For this, technologists use chemical laboratories, with the help of which the compliance of a substance with the requirements of the prescribed standard is determined.

Recently, the issues of protection environment, which is reflected in the tightening of regulations for the automotive industry and fertilizer manufacturers. In the first case, a chemical analysis laboratory assistant can work on studying the characteristics of the properties of materials used in the construction of a car, and in the second, he can identify the properties of a fertilizer that are dangerous to the soil layer.

Requirements for candidates for the position

Despite the seemingly high share of responsibility that falls on laboratory assistants, in this case the requirements for applicants for such vacancies are rather light. For example, the presence higher education is optional. It will be enough to present a diploma from a technical school or college. Nevertheless, job description a chemical analysis laboratory assistant requires very specific knowledge, without which it is impossible to fulfill the duties of this profession. In particular, the laboratory technician should know the following:

Fundamentals of chemistry, at least its general course, as well as physical and analytical directions.
Chemical-physical methods.
The device and rules of operation of devices and devices used in the process of operation.
Characteristics of radioactive substances and the nuances of handling them.
Basics of choosing methods for performing analysis.
Methods for the determination of precious metals.
Standards fire safety, labor protection and sanitary rules.

Responsibilities

Representatives of this profession are still auxiliary personnel. Nevertheless, the job description of a chemical analysis laboratory assistant provides for a fairly wide range of responsibilities, including:

Analyzes of rare metals, including rare earth and noble ones.
Performing complex analyzes of alloys according to established methods. For example, it can be nickel, cobalt, titanium and other alloys.
Arbitration analysis.
Perform analyzes of explosives using chromatographs using methods based on complex chromatogram calculation schemes.
Analysis by atomic absorption method.
Performing analyzes requiring the use of radioactive substances.
Participation in the development of new methods of analysis.
Approbation of the recommended methods
to staying.
Setting up the serviced equipment.
Acceptance of material that comes for examination.

Laboratory technicians' rights

Again, it is worth noting that the profession is quite modest in terms of leadership, and in most cases its representatives perform auxiliary tasks. Therefore, the rights are very narrowed. First of all, a laboratory assistant can submit to his immediate supervisor proposals that relate to his activities or the work of the laboratory. Also, the profession "Laboratory assistant of chemical analysis" provides for the possibility of obtaining data and methodological information from specialists for the performance of their duties. In order to achieve the highest quality analysis results, the laboratory assistant may require additional assistance in organizing research and experiments.

A responsibility

In case of non-fulfillment or unfair fulfillment of his direct functions, the laboratory assistant is responsible in accordance with the standards established by labor code RF. Such cases may include the following:

Non-compliance with safety measures, which, by the way, is especially important in chemical analyzes.
Fire safety violation.
Failure to comply with the labor regulations in force at the enterprise.

It is also assumed responsibility for other violations caused by a chemical analysis laboratory assistant during the performance of his work duties.

Grades in the profession

There are 7 categories of this profession, each of which assumes its own level of complexity of operations that a laboratory assistant can perform. The first two digits, for example, allow him to undertake the simplest homogeneous analyzes without first separating the components used. The third and fourth categories of laboratory assistants in chemical analysis increase the complexity of procedures by expanding the spectrum of substances and characteristics under investigation. For example, those with these qualifications can determine properties such as solubility, viscosity, and specific gravity. The next step allows laboratory technicians to perform sophisticated analyzes that use the very same metal alloys based on nickel, cobalt and titanium. The difference between laboratory assistants of the 7th category is an increase in the technological level of the methods used, as well as the use of specialized equipment.

Labor protection rules

In addition to general requirements, which are aimed at ensuring the safety of the chemical analysis laboratory assistant, presupposes compliance with a number of special rules.

Primarily focused on Special attention work with harmful elements and substances. Such analyzes can only be performed in rooms where a ventilation system with a forced draft hood is provided. In this case, a specific speed of suction of air flows is also established: not less than 0.5 m / s. Also, a chemical analysis laboratory assistant who works at an enterprise should receive free personal protective equipment. For example, a robe and boots are issued for a year, an apron is calculated for six months, and gloves for a month.

What is the salary?

Lab technicians cannot boast of generous wages. By the way, novice employees receive 10-15 thousand rubles. As work experience increases and, accordingly, the category, they can already claim 20-30 thousand rubles. However, higher salary levels are rare and only occur in large cities. The most promising direction for this profession can be considered the petrochemical industry. In such industries, there is a fairly intensive improvement in the qualifications of laboratory assistants in chemical analysis from the 1st-2nd to the 4th grade. In this case, the position of the head of the laboratory can be considered as the high point of a career.

Conclusion

In recent years, the profession of a laboratory assistant has been gaining a once-lost relevance and prestige. Of course, this place itself is not so attractive when compared with the work of specialists in different fields. However, a laboratory assistant in chemical analysis, whose duties in the early stages are within the capabilities of a wide range of graduates, has good opportunities for gaining experience. It is precisely as the initial stage of career formation that this profession is considered not only by scientists, but also by technologists, teachers and specialists in related fields. Of course, such work also has serious disadvantages due to close contact with chemicals. Suffice it to mention the risk of burns, allergic reactions and poisoning.
