Laser Induced Breakdown Spectroscopy System (LIBS)



Features

  • Coaxial design of excitation and collection optical paths
  • Dual Internal-External Control Mode
  • The Q signal can be output synchronously.
  • The sample chamber features a built-in 2D precision adjustment stage.
  • Adjustable lifting platform height enables inspection of samples of varying sizes.
  • System-integrated design, easy to operate
 

 

Laser selection

Solid-State Material LIBS Detection

Metal sample 
(Testing of components such as metals, alloys, steel, and ores)

High-energy pulsed laser 
E: 100 μJ to 10 mJ

The sample has good thermal conductivity, provided the laser energy is sufficiently high.

Non-metallic multi-component sample 
(Heavy metal detection in soil, analysis of nitrogen, phosphorus, and potassium fertilizers, coal quality analysis, etc.)

Low-frequency, high-energy pulsed laser 
E: 10 mJ to 100 mJ

Sample has high thermal conductivity, and is prone to chemical reactions or combustion at elevated temperatures.

Liquid Substance LIBS Detection

Liquid sample 
(Saltwater, industrial wastewater testing, etc.)

High-energy pulsed laser 
E: 100 mJ to 500 mJ

Due to the plasma shockwave effect, liquid surface fluctuations affect detection stability.

LIBS Detection of Gaseous Materials

Gas or aerosol 
(Air composition, atmospheric pollutants, vehicle exhaust, industrial emission monitoring, etc.)

Low-frequency, high-energy pulsed laser 
E: 500 mJ to 1000 mJ

The gas has a high breakdown threshold, requiring a high-energy laser as the excitation source.
