Abstract

It is shown that the only way to increase the detection capacity
of an analytical system is based on the use of the multitude
values of the single analytical signal. This can be achieved in two
modalities: 1) fixed multitude values (as mean or as sum), and 2)
sequential multitude values (as signal sum and as frequencies sum).
By using these procedures, the analytical detection can be applied
under the classical detection limit at as low concentrations as
desired, provided that the multitude of the individual values of the
signal be sufficiently high.
