Breakdownspektrometri

Breakdownspektrometri, also known as breakdown spectroscopy, is a scientific analytical technique used to identify and quantify the elemental composition of a material. This method involves the excitation of a sample's atoms or molecules, leading to emission of characteristic light spectra that can be analyzed to determine its constituents.

The process begins with the application of an energy source—such as an electrical discharge, laser, or spark—to the sample. This energy causes the atoms or molecules within the sample to become excited or ionized, resulting in a plasma or gaseous state. As the excited species return to their lower energy states, they emit electromagnetic radiation in the form of light. The emitted spectra are then collected and analyzed using spectrometers.

Breakdownspektrometri is widely utilized in various fields including environmental monitoring, metallurgy, materials science, and forensic analysis. Its advantages include rapid analysis, minimal sample preparation, and high sensitivity for detecting trace elements. Common types of breakdown spectroscopy include Spark Optical Emission Spectroscopy (OES), Laser-Induced Breakdown Spectroscopy (LIBS), and Electric Discharge Spectroscopy.

While highly effective for elemental analysis, breakdown spectroscopy generally lacks the capability to directly provide molecular information and may require complementary techniques for comprehensive sample characterization. Overall, it remains a valuable tool for rapid, in situ elemental analysis across diverse scientific and industrial applications.
