Abstract
This invention discloses a substrate enhanced laser-induced breakdown spectroscopy (LIBS) apparatus for liquid analysis. The LIBS apparatus comprises a pulsed laser for producing a laser beam, a substrate made of a material having a high absorption coefficient at the laser wavelength for receiving the liquid sample, an optical lens or mirror for focusing the laser beam onto the liquid sample to produce a plasma emission, and a spectrometer for measuring the optical spectrum of the plasma emission. When the thickness of the liquid sample reaches an optimum value, the plasma emission from the liquid sample is enhanced by the substrate to produce a strong LIBS signal for spectral analysis.
