How to quickly sort metals with handheld XRF analyzer: basic modes and methods

Sorting of metals and alloys is one of the key tasks in many processes of modern industry. Input control of raw materials, control of the composition of metals during melting, certification analysis of finished products, sorting of scrap metal – this is not a complete list of production and logistics processes that require fast and accurate analysis of the chemical composition of alloys.

Chemical composition and crystal structure that determine the performance of the alloy. Therefore, accuracy, speed and reliability have become the most important criteria for sorting metals. Together, these indicators allow you to create high-quality products, optimize the time of sorting processes and eliminate errors that entail unplanned costs.

XRF method

The method of X-ray fluorescence analysis (XRF) is the next level in the field of analysis of the elemental composition of metals and alloys. In a short time, this method has proven itself well and has gained great popularity among specialists. Being a non-destructive method, XRF allows you to quickly and reliably determine the composition of a wide range of alloys. As a result, today the XRF method performs a wide range of tasks not only in metallurgy, but also in many other industries, science and business.

One of the reasons for this success was hand-held XRF analyzers (spectrometers). This device not only guarantees the high accuracy of the XRF method, but also ensures the complete autonomy of the process. In fact, analysis becomes possible anywhere and anytime.

Key advantages of Elvatech portable XRF analyzers:

  • Mobility and autonomy. The ability to conduct an analysis at any convenient time, without being tied to a location.
  • Speed and accuracy. Handheld XRF spectrometers analyze the elemental composition of metals and alloys in a matter of seconds, providing accurate and correct data.
  • Simplicity and convenience in use. Even a minimally trained user can easily sort metals thanks to an intuitive interface and easy menu navigation.
  • Wide range of tools. Spectrometers allow you to use different modes for XRF analysis, and also contain a number of built-in options for performing additional tasks.
  • Built-in alloy library. The best XRF analyzers have an alloy library that includes information on international alloy standards, alloy composition, and impurity tolerances.

Sorting modes for metals and alloys

There are different sorting modes for metals and alloys using hand-held XRF analyzers. Each of these modes is focused on the needs of users, depending on the tasks and available resources.

PASS/FAIL mode

The simplest sorting mode is the YES/NO mode. Its essence is that the alloy is analyzed for compliance with the standards for the composition of the alloy grade available in the library. The operator selects the grade of the alloy and sets the compliance threshold in percent. In this mode, the analysis result will be obtained in just a few seconds. This made it possible to analyze a large number of samples in a short time. Such optimization is extremely useful in some production processes, when identifying defects in large-scale production.

Alloy comparison mode

The alloy comparison mode is more informative and is used in alternative cases where metal sorting requires a deeper analysis. In this mode, the user can compare the concentrations of elements in a particular grade of alloy with a previously measured composition of the sample. In this case, the comparison can be carried out both with a standard specified by the user, and with an automatically selected alloy grade that is most suitable for the measured composition. The comparison mode allows you not only to find out how the measured sample corresponds to the required standard, but also shows how much and in the concentration of which elements it differs. This mode is especially useful for monitoring the content of impurities in products, as well as for identifying an alloy of an unknown grade.

Conclusion

The XRF method makes it possible to carry out an accurate and qualitative analysis of the elemental composition of metals and alloys. The handheld XRF spectrometer is a versatile metal sorting tool that allows you to quickly and reliably determine the grade of an alloy or whether it meets established standards. The demand for the XRF method, its ease of use and a number of other advantages make the portable XRF analyzer an excellent solution for many production processes. It will become indispensable in large enterprises of various types, where there is a daily need to analyze a large number of samples.
