Chromatographic methods and related techniques

The standard deviation of the blank, sa may be considered as a measure of the noise (N) in the system. For instruments that produce a continuous, electronic output, the noise may be measured from the peak-to-peak variation (Np<->p)in the baseline signal:

Substituting eq. 2.59 into 2.58 gives:
