Ninhydrin has been the standard reagent for detecting amino acids for over 50 years. However, not all amino acids react equally well with ninhydrin, and the detection limit is ∼50 pmol (∼6 ng) of amino acid derivative. The product of the reaction of ortho-phthaldialdehyde (OPA) with ...

The sensitivity of the ninhydrin reaction is up to 0.01 percent. Modern automatic amino-acid analysis is carried out by combining the ion-exchange separation of amino acids and their quantitative identification using the ninhydrin reaction. The reaction is also used to detect each type of amino aci...
