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. |
