Different types/size geological sample can be accommodated in our Laser Ablation system because of its in-house designed sample holder. There are several requirements for the samples:
- polished 1 or ½ inch epoxy disc
- standard (7.3 x 2.5 cm) sample thin-section / or grains of sample(foraminifera shells) attached to the glass slide using carbon tape
- Semi-flat/polished slab of rocks/coral speleothems which dimensions no large than 13.8 cm by 8 cm or combination of smaller blocks with same total area. (13.5x3cm –preferable)
We have a set of NIST glass (610-614) for trace metal analyses of no ‘matrix’ challenging samples.
We also have a large collection of well-characterised carbonate standards (trace metals, Mg isotopes, U/Th, B isotopes).
