Kjeldahl method: Applications, Measurement & Standards

The Kjeldahl method or Kjeldahl digestion (Danish pronunciation: ) in analytical chemistry is a method for the quantitative determination of a sample's organic nitrogen plus ammonia/ammonium (NH3/NH4+). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement. Using an empirical relation between…
