WebDec 16, 2016 · Basically, reference material is a substance with a specific, defined characteristic that serves as a comparative value for analyses. For example, for mycotoxin analysis, reference material would be a contaminated corn or wheat sample with a clearly defined mycotoxin concentration. WebFor toxin certified reference materials (CRMs), the preferred approach is to quantitate limited amounts of scarce toxin as concentrated stock solutions by 1 H-NMR spectroscopy [28,29,30]. However, accurate quantitative NMR still typically requires mg quantities of pure toxin, which can be difficult to obtain for many compounds.
