Laser Induced Breakdown Spectroscopy (LIBS) is a fast chemical analysis technology that uses a short laser pulse (nanoseconds) to create a micro-plasma on the sample surface. This analytical technique offers many compelling advantages compared to other regular analysis techniques. This technique does not require sample preparation for measurement experience. LIBS is applicable to a wide range of sample that include metals, semiconductors, glasses, biological tissues, insulators, plastics, soils, plants, soils, thin-paint coating, and electronic materials (gas, liquid or solid state).
For this purpose, you may need:
- High energy (uJ) nanosecond pulsed laser for sample excitation: Laser power requirements will vary by sample type, as laser ablation and plasma formation are very specific to the sample.
- Individual pulse energy - uJ (INTEGRATED OPTICS)
- Individual pulse energy - mJ (CNI)
- Spectrometer (STELLARNET): tiggerable and high resolution along the range 200 - 980 nm (where emit all the substances)
- Pre-configured LIBS Systems (STELLARNET):
In addition, it is needed to synchronize the laser pulse emision with the measure, with a delay of around some microseconds for avoiding the continuum plasma spectrum.
