Understanding the Operating Principles of LIBS
How Does LIBS Work?
The operating principle of LIBS revolves around the creation of a high-temperature plasma. When a focused laser pulse strikes a sample, it vaporizes a minute amount of material, forming plasma. The emitted light consists of wavelengths corresponding to various elements within the sample. A detector captures this light, which is then processed by spectroscopic software to identify and quantify the elemental composition. This direct approach allows for instant analysis without requiring pretreatments or extensive calibration.
