Peak area calculation
Previous Up Next


A peak consists of a number of counts in adjacent channels. In principle, therefore, measurement of peak area is simply the summation of a number of channel contents over all channels within the peak, G. Subtract the underlying continuum, B to create a net area count (A) instead of the gross area.

where Ci are the counts in the ith channel, n is the number of channels within the peak region and CL-1 and CU+1 are the counts in the channels immediately beyond the edges of the peak.
