Laser ablation inductively coupled plasma mass spectrometry la icp ms enables identification and comparison of physical evidence discriminating elemental and isotopic differences at the part per billion ppb level. Laser ablation inductively coupled plasma mass spectrometry la icp ms is an analytical technique that uses direct micro scale sampling to provide high precision elemental and stable isotope analyses of solid materials. Outstanding webinar series on laser ablation chemical analysis.

La icp ms laser ablation inductively coupled plasma mass spectrometry is a powerful analytical technology that enables highly sensitive elemental and isotopic analysis to be performed directly on solid samples. New trends in laser ablation based techniques for direct solid sample chemical analysis. Laser ablation or photoablation is the process of removing material from a solid or occasionally liquid surface by irradiating it with a laser beam. Laser ablation la icp ms and libs applications in geology and geochemistry.

It is a perfect complement to any icp icp ms noble gas or stable isotope mass spectrometer. The laser beam is stationary and the sample stage is moved in x y and z directions by high precision motors that typically have stage reproducibility that is better than 1 µm. In practice laser ablation icp ms imaging is performed by rastering a pulsed laser beam across the surface of a sample. Inductively coupled plasma mass spectroscopy icp ms is an advanced analytical technique for interrogating the molecular composition of a sample at extremely low limits of concentration.

La icp ms uses a powerful nanosecond pulsed laser beam to remove material from the surface of a sample. Laser ablation inductively coupled plasma mass spectrometry la icp ms is a powerful technique for the elemental analysis of a wide variety of materials encountered in forensic casework. What is laser ablation icp ms. Featured short course at goldschmidt 2020.

What is laser ablation la icp ms. Icp ms laser ablation laser ablation la icp ms is used for the direct surface analysis of solid samples. At low laser flux the material is heated by the absorbed laser energy and evaporates or sublimates. La icp ms begins with a laser beam focused on the sample surface to generate fine particles a process known as laser ablation.
