Laser Induced Breakdown Spectroscopy

Laser Induced Breakdown Spectroscopy (LIBS)

LIBS (Laser Induced Breakdown Spectroscopy) is an extremely versatile spectroscopic technique which can be used to analyze the atomic composition of virtually any material.

In a LIBS system, a short laser pulse is used to ablate material from the surface of a sample. The laser pulse energy will be high enough to create a bright plasma on the surface of the sample. The spectrum of the plasma will contain sharp peaks corresponding to all the atoms present in the sample. The strength of the peaks will contain information about the relative concentration of the different atoms, however, advanced chemometric algorithms are typically required to perform such quantitative analyses. The lifetime of the plasma is typically 10 – 100 microseconds and the delay from the laser pulse to the creation of the plasma is typically 100 – 1000 nanoseconds. For this reason, many LIBS systems require accurate timing control.

LIBS-application

High performance and compact LIBS spectrometers

Our transmission grating based spectrometers are ideally suited for LIBS due to the following benefits:

  • Broadband and high throughput

  • Accurate and configurable timing control

  • Fast read-out

Products for LIBS

FREEDOM DUV for LIBS

Ibsen has a number of OEM spectrometer platforms available, that are well suited for integration into your LIBS analysis system. If you need a better resolution, another wavelength, or if none of the examples fit your specific needs for other reasons, we can always discuss a customized spectrometer to fit your requirements.
