| The paper describes the use of LIBS to make measurements on the output liquid from a HPLC. A well engineered rig using the HPLC output, a system to produce liquid droplets from the HPLC output, then a system to detect the falling droplets and fire the LIBS laser for analysis in a Paschen Runge/31 Photomultiplier detection system is described. However, the concentration limit measurements are made using a separate rig and and an eschelle spectrometer. | |||||
