We can provide analysis on a variety of samples, some of which have included:
...and practically any plant or animal part or piece you can think off.
The amount of material needed to perform the analysis is dependent upon the concentration of carbon, nitrogen, hydrogen or oxygen in the sample. Quantities range from approximately 0.1 mg for protein-based material to upwards of 100 mg for sediments of extremely low carbon and nitrogen content. Most materials should be dried and ground into a fine powder. In cases where filters are used for sampling, the smallest sized, pre-combusted glass fiber filter is preferable, e.g. 25 mm. Filters should be left whole, not folded, and placed into a petri dish which has been clearly labeled on both the top and the bottom. Protein-based samples may be pre-weighed prior to shipping. 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.
