Kindly include this note in your requesting letter exactly as it is:


Digestion converts nitrogen in all organic molecules to ammonia and is trapped in the form of ammonium sulphate. Ammonia is steam distilled and trapped in acid. Ammonia concentration is then determined by back titration with standardized acid.
