European Pharmacopoeia (EP) raw material identification of ninhydrin-positive compounds (NPC) using amino acids EP 2.2.56, Method 1
There are currently 17 amino acid specific monographs released for amino acids.
For each monograph it is necessary to run 2-4 calibration samples along with the raw material to be tested to determine ninhydrin-positive impurities and ammonia concentrations.
There is a base set-up fee for each amino acid monograph with an additional charge per raw material sample of the same type. One set-up can run a maximum of ten samples of the same amino acid raw material.
