Chemical analysis

Analytical analysis of non-ferrous metals and alloys is an indispensable stage of the technological process in many industries and sciences, such as metallurgy, mechanical engineering, geology, chemistry, biology. Emission spectral analysis of a metal is one of the most advanced methods for determining the chemical composition of a substance. Such a review is necessary when entering new materials and products from them into mass production, as well as at the stage of final product control.

The spectral analysis of metals is a relatively simple and universal method based on the fact that each chemical element emits a separate spectrum as it moves from one energy level to another.

The studied material is exposed to a short-term high temperature or electrical discharge, as a result of which the particles are excited and then return to their original state and energy is released. With the help of optical instruments, the radiation is decomposed into a spectrum, recorded by an analyzer and then processed by a computer program. Based on the data obtained, a conclusion is made about the chemical composition of the test sample.

Spectral analysis of metals is an important step in the quality control of raw materials and finished products, because the performance characteristics of finished metal products directly depend on the purity of the alloys used and the amount of impurities. Laboratory tests allow you to quickly and accurately determine the qualitative composition of objects, verify the compliance of materials with the requirements of industry standards.

A spectrometer is an analytical device whose principle is based on the accumulation, processing and analysis of the radiation spectrum. This spectrum is obtained by irradiating the sample and recording the resulting fluorescence. Measured length, frequency of waves, intensity of radiation.

Optical emission spectrometers are used to control the production process and product quality in metal-foundries, enterprises producing steel, copper and aluminum, factories producing equipment for the automotive and aerospace industries, and factories producing white goods.

From trace analysis in pure metals to complex alloys, optical emission spectrometers allow analysis of elements from fractions of a ppm to percent level. All important elements are measured at the same time.

The metal analyzer is used to determine the grade of metal and the quantitative and elemental composition of samples from ferrous and non-ferrous alloys. This equipment is in demand in many industries and is used at different stages of production.

The results of the conclusions regarding the compliance of the quality of materials and products with current standards are directly dependent on the readings of chemical analyzers of metals and alloys. Therefore, before purchasing this type of equipment, we recommend that you familiarize yourself with its features that will enable you to make the best choice in the future to achieve certain goals.

The division of analyzers of the chemical composition of metals and alloys into groups is carried out mainly according to two criteria. According to the principle of operation, optical emission, X-ray fluorescent and laser devices are distinguished and in place of design and application - stationary and portable. Each variety has its own characteristics and advantages.

The spectrometer principle of operation

The work of optical analyzers of metal composition is based on the technology of obtaining a spectrum, followed by measurements of the length and intensity of light waves. The research process in which these devices are used in practice is carried out as follows:

1. The sample is heated by a concentrated electrical discharge with high thermal power;
2. Due to the excitation of ions and atoms, fluorescence-accompanied thermionic emission occurs;
3. A monochromator with a diffraction grating captures light rays and determines certain chemical elements by wavelength and their number by luminescence intensity;
4.  The results obtained are displayed.

There are air working environment and argonolan emission optical spectrometers. Accordingly, they work with arc and spark discharges. Many models can work in both modes as they are equipped with different nozzles. But regardless of construction, optical emission analyzers show themselves perfectly in the study of:

• tool and low alloy steels;
• nickel, zinc, copper, cobalt, titanium-based stainless steels;
• ferritic low carbon steels;
• Aluminum and other alloys.

• Analysis of all types of samples (thinfoils 0.05 mm, wire diameter 0.1 mm.)
• 30 seconds to analyze
• Full element range: covers almost all of Mendeleev's periodic system
• Ultra-low detection limits: detection limit of all elements reaches 1 PPM.
• Time resolved spectroscopy: detection of low detection limits, inclusions, dissolved elements.
• Flexibility: any number of elements, bases, matrices without restrictions on equipment modification.

Optical emission analyzers can be well applied in the determination of low (impurity) concentrations of alloying elements (in the order of 0.0001% - 0.1%), as well as in the analysis of inclusions of non-metallic - carbon, sulfur, phosphorus, boron. Therefore, optical emission analyzers can be well applied in the analysis of carbon and low alloy steels, where the analysis of such elements is particularly important, as well as in the analysis of pure metals.

In many industries, the type of metal or alloy composition needs to be determined quickly and accurately. However, chemical analyzers are most in demand in metallurgy, petrochemical and mechanical engineering. They allow:

• To perform incoming quality control of raw materials (ingots), semi-finished products (empty), finished products (pipes, electrodes, rods, various parts) and production wastes (sawdust, metal powder) coming to the enterprises;
• Checking the chemical composition of metals during melting in the foundry;
• controlling the chemical composition of finished products in a metallurgical enterprise;
• Classification and determination of the cost of scrap metal;

No less important tasks are solved by chemical analyzers in the construction industry, especially in reverse engineering. The tools help to identify the causes of the destruction or malfunction of the latter, determining the quantitative and elemental composition of the structural components. Based on the data obtained through analyzers, designers and designers draw conclusions regarding the choice of metals and alloys for restoration work or the manufacture of new structures.
