Development and field testing of laser-induced breakdown spectroscopy for in situ multi-element analysis during underwater surveys

The application of laser-induced plasmas has been investigated as a method to perform in situ, multi-element chemical analysis of liquids and immersed solids at sea during marine surveys. Analytically useful spectra have been observed from plasmas generated by irradiation of a high power pulsed laser in both bulk liquids and immersed solids using a single pulse at hydrostatic pressures of up to 300atm. Experiments were performed at sea using the in situ laser-induced breakdown spectroscopy (LIBS) device I-SEA (In situ Seafloor Element Analyser) mounted on-board the remotely operated vehicle (ROV) Hyper-Dolphin of the Japan Agency for Marine Science and Technology (JAMSTEC). During the trials real-time, multi-element analysis was successfully achieved for the first time at sea using LIBS for both liquids and immersed solids at a depth of 200m.

Abstract

The application of laser-induced plasmas has been investigated as a method to perform in situ, multi-element chemical analysis of liquids and immersed solids at sea during marine surveys. Analytically useful spectra have been observed from plasmas generated by irradiation of a high power pulsed laser in both bulk liquids and immersed solids using a single pulse at hydrostatic pressures of up to 300atm. Experiments were performed at sea using the in situ laser-induced breakdown spectroscopy (LIBS) device I-SEA (In situ Seafloor Element Analyser) mounted on-board the remotely operated vehicle (ROV) Hyper-Dolphin of the Japan Agency for Marine Science and Technology (JAMSTEC). During the trials real-time, multi-element analysis was successfully achieved for the first time at sea using LIBS for both liquids and immersed solids at a depth of 200m.
