Development and field testing of laser-induced breakdown spectroscopy for in situ multi-element analysis at sea

The application of laser-induced plasmas has been investigated as a mechanism 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 30MPa. 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 sea trials real-time, multielement analysis was successfully achieved for the first time for both liquids and immersed solids at a depth of 200 m.

Abstract

The application of laser-induced plasmas has been investigated as a mechanism 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 30MPa. 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 sea trials real-time, multielement analysis was successfully achieved for the first time for both liquids and immersed solids at a depth of 200 m.
