Detection of Li in synthetic slags of Li-ion batteries by laser ablation inductively coupled plasma time of flight mass spectrometry (LA-ICP-ToF-MS) Lithium is one of the most important technological elements and is mainly used in Li-ion traction batteries (LIBs). Due to its high oxygen affinity, recovering this element from, e.g., batteries is a challenge. In pyrometallurgical processes, Li accumulates in the slag and is currently largely lost.

Fine-tuning of LA-ICP-QMS conditions for elemental mapping For high-speed and high-resolution elemental LA-ICP-QMS mapping it is important to select the optimal operational conditions to avoid aliasing, minimize blur and maximize the signal-to-noise ratio. An earlier paper already highlighted the fundamentals involved in the selection of these conditions (J. Anal. At. Spectrom., 2019, 34, 1919); this work will fine-tune these conditions using the principle of divisors.

Analytical performance of a high-repetition rate laser head (500 Hz) for HR LA-ICP-QMS imaging With the advent of low dispersion, fast aerosol transport technologies used in laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), the need for high-repetition rate lasers became crucial.
