摘要：

The use of laser ablation ICP-MS (LA-ICP-MS) is now an accepted technique for direct solids analysis of bulk and discrete geological and related samples. For this application there are several requirements controlling analytical performance:a. Very high sensitivity of the detector system and efficient manipulation of transient signals. b. A robust UV Nd-YAG laser capable of producing 10 micron size ablation craters with minimum fractionation effects.
