Peak Finder
The Peak Finder program is a LabView application (compiled to a Windows .Exe) that can be used to compute the peak capacity of chromatographic separations. The peak capacity is defined as the number of compounds that can be separated with baseline resolution in a given separation space. The Peak Finder uses a robust method for computing peak capacity, fitting all of the peaks in a chromatogram with a Gaussian peak, then computing the median peak width of each peak and dividing the separation space (time) by the median peak width. The user can step through the program and examine the fit for each peak, modifying the peak width and elution time for each peak so that the Gaussian peak best represents the actual peak. Peaks that the program found but are not real peaks can be excluded from the peak list and thus all subsequent calculations.
