Hi everyone,
i would like to extract some elements and molecule from soil for an Continuous-Flow Analysis (Futura, AMS Alliance) but for these analysis I only have very little material (about 0.1g). It is dust from the Sahel as part of a project on erosion. I want to analyze PO4 (Olsen extraction method and colouring of a phosphomolybdic complex ), NH4 (2M KCl extraction, Salicylate method on CFA), total phosphorus (HCl method) and NO3/NO2 (2M KCl method, cadmium reduction method). For quantification Do you think I can do these analysis with so little material? I’m open to advice.
Thank you so much
Dear Yoan,
What you want to do is not possible using conventional techniques.
However, you may be able to use a series of micro-scaled, sequential extraction techniques. These will be approximations even if you do parallel validation experiments using similar materials with known properties.
If you wish I'll think more about the question, Paul.

Thank's a lot for you answer Paul.
I had some idea that it would be complicated and your answer confirms my fears. The solution you are proposing deserves to be tested. I’ll look into it. Thank you very much.
If you have any advice, I’m obviously interested.
