In the cover article of the May, 2017 issue of Spectroscopy, members of our icpTOF team describe recent advances in laser ablation (LA) and ICP-MS technology that are enabling high-speed, multielemental imaging of biological and geological samples on the micrometer scale.    In particular, this movement has been driven by simultaneous improvements in (i) the design of fast-washout laser ablation cells and (ii) the speed and sensitivity of time-of-flight (TOF) mass spectrometers.

The authors demonstrate the state-of-the-art in LA-ICP-MS imaging by coupling a TOFWERK icpTOF with fast-washout LA systems from ESI and Teledyne Cetac for two different analyses.   The first experiment looks at trace elements in a polished thin section of the mineral sphalerite (ZnS) displaying distinct internal growth zoning.    Imaging of the 1 x 2 mm area with 5-um resolution clearly reveals distinct distribution patterns for different elements.   In the second example, a thin section of a rat kidney that was perfused with the anti-tumor agent cisplatin is imaged in order to examine distribution of Pt across different regions of the kidney.

The authors conclude that “Because of the recent technological advances in laser-ablation cell design and time-of-flight mass spectrometry, the method of LA-ICP-TOF-MS for high-speed, high-spatial resolution, multielemental imaging is poised to become an important analytical tool for researchers from various scientific disciplines. The recent progress will be further exploited by the development of high-performance data reduction software to support spot-resolved quantification strategies.”
