We have been asked to run some soil samples taken from a salt marsh in Australia, the majority of which are from the surface, but there are also some from a core. The samples have been dried and ground and analysed for TOC.
Based on a requirement of 400 ug carbon per sample for our system (Sercon 20-22), some of the samples will require between 5 and 15 mg of soil per capsule. I spend the majority of my time working with collagen in the 1 mg range, so this venturing into the unknown.
For those of you working with soils, is there anything I need to be aware of when running this type of material for delta 13C, and how much material per capsule is too much?
Many thanks for any assistance.
