WebThe valley to peak ratio (V/P ratio) is proposed as a measure for the extent of separation of two chromatographic peaks. This quantity is compared with the resolution (R). For two Gaussian curves, a mathematical relation exists between the two quantities. The V/P ratio has a larger coefficient of variation than the resolution, thus being the more sensitive … WebLa méthode HIC est un type de chromatographie en phase inverse utilisé pour séparer les grosses biomolécules, telles que les protéines. Il est généralement souhaitable de maintenir ces molécules intactes dans une solution aqueuse, en évitant tout contact avec des solvants organiques ou des surfaces susceptibles de les dénaturer.
