Types of spectroscopy

Spectroscopy is the scientific method for the investigation and measurement of the interaction between matter and electromagnetic waves. This technique is of fundamental importance in many fields of science and technology, as it enables the analysis of the composition and properties of materials at the molecular and atomic level. We offer a wide range of spectrometers specifically designed for various spectroscopic methods such as LIBS, MID-IR, NIR, and Raman spectroscopy. In this article, we provide an overview of these different types of spectroscopy and their applications.

LIBS spectroscopy (laser-induced breakdown)

LIBS spectroscopy, known as laser-induced breakdown spectroscopy, is an especially efficient analytical method that requires no sample preparation and offers extremely fast element analysis. Our LIBS spectrometers are equipped with the following features: Atom Trace They use a high-energy laser to precisely vaporize and ionize a small amount of the material to be examined. This process generates a plasma that releases specific light emissions. The emissions are carefully analyzed to accurately determine the elemental composition of the respective sample. Thanks to their outstanding capabilities, our LIBS spectrometers are particularly suitable for rapid in-situ analyses that are essential in fields such as metallurgy, environmental monitoring, and forensics. For example M-Trace is a mobile device with simple operation for quick on-site element analysis.

MID-IR spectroscopy (Mid-infrared spectroscopy)

MID-IR spectroscopy is particularly useful for chemical identification and quantification, as it can detect functional groups in molecules. Our MID-IR spectrometers are equipped with: block engineering They use infrared light to trigger molecular vibrations, which are then detected as unique absorption patterns in the mid-infrared range. This makes them indispensable for applications in the chemical process industry, pharmaceuticals, and food technology. For example, our MID-IR spectrometer is able to record an IR spectrum over 1100 1/cm in just a few seconds. This new technology opens up additional possibilities in molecular spectroscopy and process monitoring.

NIR spectroscopy (Near Infrared)

NIR spectroscopy enables fast and non-destructive analyses and is frequently used for quality control in the agricultural, food and pharmaceutical industries. Our NIR spectrometers from broom rose measure the absorption of near-infrared light, which penetrates deep into the sample and provides valuable information about composition and quality. For example, Handheld NIR spectrometers It is ideal for non-destructive and contactless testing and is a powerful tool for quality control and process monitoring.

Raman Spectroscopy

Raman spectroscopy is known for its ability to provide molecular information without destroying the sample. It is based on the Raman scattering of monochromatic light, such as laser light. Our Raman spectrometers are equipped with: Enwave It detects the specific frequency shifts in scattered light to identify molecular fingerprints. This technique is of great value in materials science, biomedicine, and environmental engineering.
The hand-held ARX MK2 from Serstech On the other hand, it is a powerful, portable Raman spectrometer for material testing, goods inspection and for the laboratory.

Conclusion

Spectroscopy encompasses a variety of analytical methods for investigating the composition and properties of materials. Depending on the measurement task, LIBS, MID-IR, NIR, and Raman spectroscopy provide different information – from the elemental composition to the molecular structure.

While LIBS is particularly suitable for rapid element analysis, infrared and Raman spectroscopic methods enable the identification and characterization of chemical substances. The choice of the appropriate method depends, among other things, on the sample, the information required, the measurement speed, and the environmental conditions.
