Laser Ablation Icp Ms

The nwr213 is an affordable no compromise instrument suitable for a wide range of applications.
Laser ablation icp ms. La icp ms uses a powerful nanosecond pulsed laser beam to remove material from the surface of a sample. 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 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 la icp ms.
What is laser ablation icp ms. Laser ablation la icp ms and libs applications in geology and geochemistry. The agilent 7800 and 7900 single quadrupole icp ms and 8900 triple quadrupole icp ms icp qqq systems provide high sensitivity fast acquisition speed and 10 11 orders dynamic range. 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.
New trends in laser ablation based techniques for direct solid sample chemical analysis. It is a perfect complement to any icp icp ms noble gas or stable isotope mass spectrometer. 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. 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.
The industry s gold standard in 213 nm solid state laser ablation. At low laser flux the material is heated by the absorbed laser energy and evaporates or sublimates. Icp ms laser ablation laser ablation la icp ms is used for the direct surface analysis of solid samples. Outstanding webinar series on laser ablation chemical analysis.
La icp ms begins with a laser beam focused on the sample surface to generate fine particles a process known as laser ablation. Featured short course at goldschmidt 2020. Advanced polymer analysis using la icp ms and libs. 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.
