Abstract

The statistical moments of an experimental chromatographic peak are commonly computed by using a summation procedure. In general the random errors In the observed signal far exceed those in the measurement of time. Under this condition it is possible to use the method of error propagation to derive simple equations for the uncertainty in the statistical moments and thereby circumvent the problems Inherent in previous stochastic experiments. The equations can be used to design a data sampling program capable of achieving any desired precision.
