Specific volumes of pure ammonia under the pressure corresponding to saturation have been determined from -78° to 100° C. The method employed is similar to one previously used by Dieterici, and consists essentially in observing, at various temperatures, the volumes of the liquid and vapour phases in equilibrium in a closed vessel.

Ammonia: inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer Ammonium hydroxide: aqueous ammonia; used in traditional qualitative inorganic analysis: Azobisisobutyronitrile: organic compound; often used as a foamer in plastics and rubber and as a radical initiator: Baeyer's reagent
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

Chemical ionization can also be used to identify and quantify an analyte present in a sample, by coupling chromatographic separation techniques to CI [3] such as gas chromatography (GC), high performance liquid chromatography (HPLC) and capillary electrophoresis (CE). This allows selective ionization of an analyte from a mixture of compounds ...
The Kjeldahl method or Kjeldahl digestion (Danish pronunciation: [ˈkʰelˌtɛˀl]) in analytical chemistry is a method for the quantitative determination of a sample's organic nitrogen plus ammonia/ammonium (NH 3 /NH 4 +). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement.
All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.
