Laser-Ablation Quadrupole Inductively Coupled-Mass Spectrometry

Laser Ablation Quadrupole ICP–Mass Spectrometry (LA-ICP-MS) is a state-of-the-art analytical technique that enables the rapid determination of multiple elements at ultra-trace concentrations. With its combination of low detection limits, high sensitivity, and fast throughput, LA-ICP-MS has become one of the most widely applied methods for the geochemical and isotopic investigation of Earth materials. Applications range from mapping trace element distributions in minerals, to quantifying isotopic ratios for geochronology and thermochronology, to probing elemental signatures that record geological processes such as magmatism, metamorphism, and weathering.

The Melbourne Thermochronology LA-ICP-MS Laboratory is equipped with an ESL ImageGeo 193 nm Excimer Laser system, coupled with Laser-Induced Breakdown Spectroscopy (LIBS) capabilities, and an Agilent 7700x Quadrupole ICP-Mass Spectrometer. This integrated system provides researchers with:

• High-precision trace element analysis across the periodic table, including difficult-to-measure light elements.

• Spatially resolved microanalysis, allowing elemental mapping and depth profiling of individual mineral grains.

• Versatility for both conventional U-Pb zircon and apatite dating, as well as innovative applications such as thermochronology, trace element thermometry, and elemental imaging.

Together, this facility delivers world-class analytical performance, supporting cutting-edge research in geochronology, thermochronology, and broader Earth and environmental sciences.
