The
Integration time
refers to the period of time for which the data is collected to provide a
data point and is a compromise to optimize the resolution while minimizing the noise in the
spectrum. A short integration time will optimize the resolution; however the noise may be
relatively high. If a long integration period is employed, the resolution may be compromised
and small features in the spectrum may be lost, however the noise in the spectrum is
reduced.
The optimum integration time for the present set of conditions can be obtained by pressing
the
Optimize Integ. Time
button. The analyzer must be in
Backpurge
mode before the
spectrometer’s integration time can be optimized.
If desired, the operator can select the integration time by selecting the
Set Integ. Tim
e button;
this will present the
Integration Period
dialog box to set the time.
The Panorama field can be used to select a sub-section of the spectrum for viewing. To
zoom in on a section of the spectrum, click the Stop Polling check box and then use the
mouse to draw a box around the area of interest.
The Save Spectrum button accesses a dialog box to save the present spectrum in CSV
format.
5.2.5 Absorbance Page
The Absorbance page (Figure 5-8) presents the Absorbance spectrum and reports the
concentration of H
2
S, SO2, COS and Sulfur Vapor
.
The range can be edited on the
Config
panel (Section 4.8).
