5 Most Common Types of Laser-Induced Breakdown Spectroscopy Techniques

Laser-induced breakdown spectroscopy (LIBS) is an analytical technique that is used to identify the elemental composition of a sample. LIBS works by using a high-powered laser to create a plasma on the surface of the sample being analyzed. As the plasma cools, it emits light, and this light is analyzed to determine the elemental composition of the sample. There are several types of LIBS techniques that are commonly used in various fields. In this article, we will discuss the five most common types of laser-induced breakdown spectroscopy techniques.

1. Single-Pulse LIBS

Single-pulse LIBS is the most basic and commonly used LIBS technique. In this technique, a high-powered laser is used to generate a plasma on the surface of the sample being analyzed. The plasma emits light, and this light is collected and analyzed to determine the elemental composition of the sample. Single-pulse LIBS is relatively fast and can analyze a wide variety of samples, including solids, liquids, and gases.

2. Double-Pulse LIBS

Double-pulse LIBS is a more advanced version of single-pulse LIBS. In this technique, two lasers are used instead of one. The first laser is used to generate a plasma, and the second laser is used to heat the plasma and produce a more intense emission spectrum. Double-pulse LIBS is more sensitive than single-pulse LIBS and can detect trace amounts of elements in a sample.

3. Standoff LIBS

Standoff LIBS is a type of LIBS that is used to analyze samples from a distance. In this technique, a high-powered laser is used to generate a plasma on the surface of the sample
