Detection of lithium using SIMS on FIB microscope

The EQS spectrometer provides SIMS detection for focusedion beam (FIB) microscopes, with excellent sensitivity for light elements (sub ppm sensitivity for lithium).

Overview

The EQS spectrometer provides SIMS detection for focused ion beam (FIB) microscopes, with excellent sensitivity for light elements (sub ppm sensitivity for lithium).

Additionally, isotopically pure materials can be used for diffusion studies.
