| Double Pulse LIBS was used to analyse beryllium in samples made by compressing soil into pellets. The 313.04nm line was preferred due to interferences at the other strong lines (234.86nm, interference with Fe; 332.11nm interference with Ti). Detection limit for 355nm was a factor of 3 better than with 532nm laser. | |||||
