Abstract
A new method of reducing the errors associated with peak area integrat ion has been developed. This method utilizes the signal content of eac h channel as an estimate of the overall peak area. These individual es timates can then be weighted according to the precision with which eac h estimate is known, producing an overall area estimate. Experimental measurements were performed on a small peak sitting on a large backgro und, and the results compared to those obtained from a commercial soft ware program. Results showed a marked decrease in the spread of result s around the ''true'' value (obtained by counting for a long period of time), and a reduction in the statistical uncertainty associated with the peak area.
