An example of the automated peak find capability of ChromaTOF for a complex ink sample is seen
in Figure 1. Each vertical line with a number represents a found peak, and evenwhere there are
significant coelutions (some of the peak apexes are onlyms apart), peaks were easily located.

Automated peak findwith ChromaTOF. Each numbered vertical line is a peakmarker.
Even though there are obvious coelutions, ChromaTOF located the peaks.
