Application

It can be used as an analytical standard to: Evaluate Kjeldahl′s procedure to determine total protein content of reference standards used in clinical laboratories. Analyze beer and wine for their protein and total usable nitrogen using a microwell ninhydrin assay. Compare Kjeldahl and Dumas methods for routine analysis of dairy products in an interlaboratory study. Simultaneously determine total phosphorus and total Kjeldahl nitrogen in surface water samples. Quantitatively determine nitrate in surface waters using Valdetrama method. Measure low level Kjeldahl nitrogen using an AutoAnalyzer.
