Presentation - Association of Public Analysts

Nitrogen / Protein Determination by Combustion

Variables Development • Extraction solvent Variation of water: IDA ratio Too much IDA gives poor peak shape Too little IDA gives poor recoveries for NHDC and aspartame Optimum 75:25 (by volume) water: IDA

Development • Clarification using Carrez reagents • pH Use has little effect on chromatography. Use gives much lower NHDC recoveries. Little variation in recoveries over the range 3-8 except for aspartame. Aspartame most stable at pH 4, at pH 7 decomposition is rapid.
