WebNov 20, 2015 · Amino acid analysis, (AAA), and elemental analysis (CHN). AAA only requires minimal amounts of peptide while CHN consumes milligrams of peptide. CHN analysis on the other hand is far more accurate. In fact, it may be debated whether or not AAA is much better than making an educated guess. WebElemental analysis can be subdivided in two ways: Qualitative: determining what elements are present or the presence of a particular element. Quantitative: determining how much of a particular or each element is present. In either case elemental analysis is independent of structure unit or functional group. 1.2: Spot Tests cut lemons in fridge
