Exum Instruments

It uses a patented dual-laser method, laser ablation laser ionization time-of-flight mass spectrometry, to measure elements from lithium to uranium without dissolving the sample. For battery work, Massbox maps lithium across an electrode and profiles it through coatings and SEI layers, and it runs under vacuum so cycled electrodes and solid-state electrolytes can be measured without air exposure.

The company is based in Denver, Colorado, and also sells to mining, additive manufacturing, defense and nuclear users. Thermo Fisher Scientific handles sales, distribution and support for Massbox in Europe and China.
