Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS)
The New Wave UP193 Laser Ablation unit is capable of introducing almost any type of solid sample into the ICP-MS, thus providing the capability to detect and quantify up to 70 elements of the periodic table in a solid. It is especially applicable to in-situ analyses for projects requiring the determination of spatial variation of elements within a sample. Laser ablation is capable of sampling rasters, individual spots, grids of spots, lines and even curved patterns through/across a sample. The system is computer controlled. The video imaging system is equipped with both reflected and transmitted light.
Materials studied at this facility include bird feathers, shells, tree rings, otoliths, steel, circuit boards, clay particles, and pressed powders.
Laser Ablation is a technique utilized to introduce solid samples into an Inductively Coupled Plasma Mass Spectrometer. The sample is ablated with a solid state pulsed laser beam, creating an aerosol which can be transported into the 8000K argon plasma. The sole function of the plasma is to ionize the sample. The ions are then introduced into a mass analyzer and separated and collected according to mass to charge ratio.
Samples are typically mounted on a petrographic slide, as seen with the otoliths at left, but other configurations are possible.
Analytical and Technical Services analyzes samples from an array of customers including academic researchers within ESF and from other regional institutions, government agencies, and private enterprises.
