Advantages of Laser Induced Breakdown Spectroscopy

LIBS is considered one of the most efficient and user friendly analytical techniques for trace elemental analysis in gases, solids, and liquids. Some of its major advantages include:

  • Real-time measurements: online monitoring and quality control of industrial processes
  • Noninvasive, nondestructive technique: valuable samples can be reused, sensitive materials can be analyzed, suitable for in-situ biological analysis
  • Remote measurements can be done from up to 50 meters distance: can be used in hazardous environments and for space exploration missions on other planets
  • Compact and inexpensive equipment: can be widely used in industrial environments, perfect for field measurements
  • High-spatial resolution: can obtain 2D chemical and mechanical profiles of virtually any solid material with up to 1 µm precision
  • Non or very little sample preparation is required: reduced measurement time, greater convenience, less opportunity for sample contamination
  • Samples can be in virtually any form: gas, liquid, or solids
  • Analysis can be performed with a very small amount of sample (nanograms): very useful in chemistry for characterization of new chemicals and in material science for characterization of new composite materials or nanostructures
  • Virtually any chemical element can be analyzed, such as heavier elements unavailable for X-ray fluorescence
  • Analysis can be done on extremely hard materials like ceramics and superconductors; these materials are difficult to dissolve or sample to perform other types of analysis
  • In aerosols both particle size and chemical composition can be analyzed simultaneously
