Abstract: A dual source system and method includes a high power laser used to determine elemental concentrations in a sample and a lower power device used to determine compounds present in the sample. A detector subsystem receives photons from the sample after laser energy from the high power laser strikes the sample and provides a first signal. The detector subsystem then receives photons from the sample after energy from the lower power device strikes the sample and provides a second signal. The high power laser is pulsed and the first signal is processed to determine elemental concentrations present in the sample. The lower power device is energized and the second signal is processed to determine compounds present in the signal. Based on the elemental concentrations and the compounds present, the compounds present in the sample are quantified.

Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus and method for performing spectral imaging of a sample surface. A high repetition rate pulsed laser is employed to produce a train of laser pulses. The laser beam is then scanned by a scanning mechanism over a surface of the subject sample. Each laser pulse produces a LIBS signal from a specific position of the sample surface, which is then measured by a spectrometer device to obtain a LIBS spectrum. The position of the laser beam is recorded and correlated to the corresponding LIBS spectrum. A two dimensional (2-D) mapping of the sample surface to its LIBS spectra is acquired in this manner to construct a LIBS spectral image of the sample surface.
