| The authors use a Nd:YAG and Nd:YALO (wavelength=540nm, pulse energy 60mJ) in a double pulse LIBS configuration to improve the detection limits for LIBS analysis. DP-LIBS was chosen due to possibility of field deploying this configuration (as compared to UV detection systems or He gas atmosphere, which are less possible outside of the laboratory). | |||||

| Cl | 50.0000 (None) | 837.6000 | N/A | None | -10.0000--10.0000 | The authors had some interference from third order diffraction of Mg II lines at 279.55nm and 280.27nm. Best results from 4us delay between laser pulses. The Mg peak at 279.08nm was used as a normalisation/reference to reduce pulse to pulse fluctuations. |
