1 Answer

Answer :

answer:Hmm, depends on the college, but it’s plausible. An HPLC/MS setup, common in a university (even teaching labs) could get it done. As for how to do it, you’d dilute the hummus and extract it, probably using a strong acid or base to help dissolve the components, and inject that on an HPLC column. Do that along with an uncomtaminated hummus, and determine if any components are different. If so, take that peak, inject into an MS or MS/MS, and compare the mass of that compound against common toxins, or against the probable toxin if the toxicology of the subject is known. Alternately, simple solubilize the hummus as above and just inject into an MS, selecting for the masses of possible/probable toxins. Hits indicate that it’s possibly there (again, run verses normal hummus for more clarity).
