Screen your zircon chronology samples effectively

Use CL intensity maps to easily distinguish zircon grains from the surrounding host material and reveal their intragranular structure and zonation patterns. Employ the large-area spectroscopy imaging mode to identify regions of interest and leverage CL as an efficient screening tool before proceeding to isotope analysis through mass spectrometry or atom probe tomography.

Sedimentary rocks

Perform micro-characterization of sedimentary rocks

Use cathodoluminescence (CL) imaging to quantitatively map the quartz, carbonate, or apatite composition of sedimentary rocks to enable further analysis, including segmentation of granular material and cemented material. Benefit from the unique CL responses of these minerals and use CL for your inhomogeneous mixed samples as well.
