The statistical accuracy and the consistency under
varying levels of background intensity are experimentally
compared for six simple methods of peak area integration.
Partial peak area methods (PPA) of the Wasson type yield
better statistical accuracy under fixed conditions than
methods based on total peak area determination (TPA), but
display a negative bias with increasing background
intensity. A new partial peak area determination method
based on variable summing width, continuous monitoring of
FWHM and linear interpolation between channels is
proposed and tested. The proposed method compares
favourably with established methods, combining the good
statistical accuracy of PPA methods with the consistency
of TPA methods. The experimental results indicate that
theoretical error estimates based on simple Poisson
statistics are inadequate.
