Using Resamplewith sample reduction rates of 2, 5, and 10 (a dialog box demonstrating this, with
retention time andmass range reductions, is shown in Figure 6) better peak responses are seen for
BDE 209 (Figure 7). Asmentioned earlier, this enhanced peak response is due to spectral
summing.

Dialog box showing Resample
for BDE 209. Because the data
acquisition rate was too fast for the
broad peaks, a sample reduction rate of
2was used for the retention time range
for where BDE 209 eluted.

Linear chromatograms for
modulated BDE 209 at original acquisition
rate of 50 spectra/second (orange) and
when sample reduction rates (of 2, 5, and
10) were used in the ChromaTOF Resample
feature to produce new files at 25 (green),
10 (red), and 5 (blue) spectra/second. The
enhanced peak responses are due to spectral
summing.
