BNEIR can do initial analyses on existing sections or blocks that you may have already prepared:
Because LA-ICP-MS is a surface technique, make sure there are no cover slips on any sectioned tissue. Paraffin blocks can be also used, but make sure the block is faced so that the sample is at the surface. It’s preferable to section paraffin blocks (20 µm approximately) for complete, quantitative ablation. We avoid stained tissue because stains contain inorganic elements that confound the analysis.
H&E SECTIONS: If you have adjacent H&E sections of your samples, sending scanned images to BNEIR can be used for co-registration with your elemental mapping data.
If you don’t have specimens prepared: The quick start guide below will help you quickly find published methods for the best way to prepare your specimens for LA-ICP-MS analysis.
