In this paper, le dosage colorimetrique des acides amines separes par chromatographie sur papier is effectue par un reactif a la ninhydrinehydrindantine apparente a celui de Moore & Stein.Abstract:
Le dosage colorimetrique des acides amines separes par chromatographie sur papier est effectue par un reactif a la ninhydrinehydrindantine apparente a celui de Moore & Stein. Les ions ammonium contenus dans le papier sont elimines avant le dosage par vaporisation d'une solution de potasse methanolique et sechage, ce qui permet de rendre nulle la valeur a blanc du papier lors du dosage. La methode permet de doser de 0,02 a 0,5 micromole d'acides amines.read more

TL;DR: In the present investigations of the chromatographic separation of amino acids, it has been observed that, when the color development is carried out in tubes exposed to the air, these difficulties appear to result primarily from the influence of dissolved oxygen.
