Topics - Peak
In chromatography, peak is the name originally used by James and Martin to describe the elution curve of a solute which relates solute concentration in the mobile phase with time. This term was obviously evoked by the Gaussian shape of the elution curve. Subsequently, the term peak was used for all types of elution curves, whether they related concentration of solute or mass of solute eluted to time or to the volume of mobile phase passed through the column. In addition, the term peak is now given to all shapes of elution curves whether they be Gaussian or not.
