Sample types typically include organic samples (C,N,O,H), inorganic samples (e.g. carbonate for C and O), and water for O and H. We also provide isotopic analyses of individual compounds (e.g. fatty acids and amino acids). The addition of our LA-MC-ICPMS system allows us to perform isotopic analyses of heavier elements, such as strontium, using either a solution method or by laser ablation.
We provide isotopic analyses of a wide variety of modern and ancient samples, including: muscle, feathers, otoliths, blood, bone collagen, whale baleen, algae & zooplankton, soil & sediment, whiskers & claws, dissolved organic carbon and nitrogen, water, vegetation - practically anything!
The amount of material needed to perform the analysis is dependent upon the concentration of carbon, nitrogen, hydrogen or oxygen in the sample. Most materials should be dried and ground into a fine powder, except filters. Below are some general guidelines, but please contact us for details regarding sample preparation.
Our facility is outfitted with a variety of equipment available to customers to use to accomplish their sample preparation. These include microbalances and equipment for sample drying, grinding and powdering, acid treatment and a variety apparatus for extractions. Three micro-balances in a dedicated weighing room at ASIF are available to all investigators to allow samples to be weighed. ASIF lab space is also available at both the light and heavy isotope labs to support investigators in preparing samples for analysis at ASIF.
