| Quantitative elemental determination in water and oil by laser induced breakdown spectroscopy | Pascal Fichet, Patrick Mauchien, Jean-François Wagne, Christophe Moulin | Oil | Princeton Instruments ICCD Max | THR Monochromator | Visual Basic |
| Laser: | Nd:YAG 532.0000nm 60.0000mJ 1.000Hz |

| Gate Delay: | 0.500us | ||||
| Gate Width: | 25.000us | ||||
| The laser beam was directed at an angle to the liquid surface to reduce splashing, and the slower rep rate (1Hz) also improved reproducibility. Calibration curves were constructed by ratioing the peak to the background intensit | |||||
