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. |
