Graphical representation of signals provided by flow systems

1 Graphical representation of signals provided by flow systems 

I = injection point h = peak height A = peak area fresidence = residence time fstart = Start time 

W = peak width at a given signal level fFi/2 = peak width at half-height 

The shape of a typical analyte peak can be defined in mathematical terms by using a like function such as 

Typical analytical signal (peak) obtained with flow techniques.
