9.3 Signal-to-noise Calculation
Use the quick load option shown in Figure 5.2 to load the BZP data file into
MSDR. Plot a single ion chromatogram of the m/z 362 ion. Refer to Figures 5.3
and 5.4 but be sure to plot ion m/z 362. Click the apex scan to display the
spectrum. Refer to Figures 5.10 and 5.11 and background correct the spectrum.
Right mouse click the apex scan and select Calculate Noise (refer to Figure 5.5).
The RMS signal-to-noise calculation will be performed for the scan closest to
where the cursor was placed for the right mouse click. Use 5 Point Savisky Golay
smoothing. A passing signal-to-noise calculation is shown in Figure 9.1.
