The authors explore the use of both Double and Single Pulse LIBS for the detection of As in soils. As Peaks at 188.979nm, 200.335nm and 228.812nm were tested, with the best results coming from the 228.812nm peak. Calibration was via the spiking of a standard soil, but the unknowns were a range of soils collected from mine sites around Korea.
