KjeldahlKjeldahl is an analytical chemistry technique for the quantitation of nitrogen in chemical substances. Applications of Kjeldahl include analyzing the protein content of food, nitrogen analysis in environmental sciences and the pharmaceutical industry and total kjeldahl nitrogen, nitrate and ammonia analyses in agricultural sciences.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Nitrogen
