Data Analysis and Reporting
The data processing was performed using TraceFinder
™
quantitation software. TraceFinder software contains a
compound data store containing a large number of
pesticide compound entries from which required compounds
for the method had been selected. For each pesticide, the
necessary parameters for MRM acquisition and compound
identification, such as SRM transition, retention time, and
ion ratios, as well as quantitation details like quantitation
mass and recovery requirement, are stored.
The analytical sequence setup, data acquisition and result
processing was done from one software platform
integrating the complete analytical process. In Figure 6,
the analytical sequence is shown in the upper part of the
screen, with the compounds included in the method to the
right. The actual chromatograms for the selected pesticide
compounds are displayed in the bottom part for review by
the operator.
