| Trace elements in a liquid jet were analysed using LIBS. A bulk liquid was also analysed, but the LODS were higher due to splashing. Comparisons were also made of optimal conditions in both jets and static liquids. Optimal gate delay and with were determined for each element and used in their LOD determination. Based on comparative results a LOD for TC of 1ug/mL was estimated, however this was not confirmed experimentally. | |||||
