Instrumental analytical methods are studied from the point of view of the information content of the signal, whose intensity or both position and intensity are sources of relevant information. The information content is expressed with the aid of the divergence measure in units defined by the unit isoinform. If both the intensity and the position of the signal are sources of information, it is assumed that they are mutually independent or that the measurement of the signal intensity is carried out with accuracy which depends on the signal position.
