Material can be analyzed in solution or it can be analyzed as a solid by laser ablation.
Solids
In contrast to some other analytical methods (e.g., SIMS), no special sample preparation or storage is required. For example, thin sections can be examined in the lab with an optical microscope and then transferred directly into the laser cell, with in situ analysis underway in minutes.
How to Prepare Samples
How to Prepare Thin Sections For Analysis
1. Image the thin section and mark the grains of interest
2. Image each individual grain of interest with BSE or another imaging technique. Always place the grain of interest in the center of the image. For monazite and zircon, you MUST create a zoomed-out image (see below):
and a second, zoomed-in image (again, below).
3. Image each individual grain with either BSE (titanite, rutile), CL (zircon), or x-rays (monazite, xenotime, allanite). Below is an example set of an x-ray images for monazite:
Below is an example BSE image of a titanite:
