Abstract
Techniques de mesure chromatographiques et optiques. Un échantillon contenant un constituant à analyser est fractionné par une colonne chromatographique où l'on mesure le taux d'absorption (ou de transmission) de la lumière. Le véhicule (solvant) qu'élue à travers la colonne augmentant le taux de transmission en raison d'une différence entre les indices de réfraction respectifs du fluide porteur et du matériau de garnissage chromatographique, la mesure est compensée pour annuler cet accroissement du taux de transmission de manière à permettre une mesure de telles traces de constituants. Application particulière à la recherche de traces d'hémoblobine lysée dans du plasma sanguin.
