The X and Y coordinates of a data point on the curve can be determined by moving the
mouse over the desired point on the spectrum.
The Display Factory Reference check box is used to indicate that the factory reference
spectrum should be superimposed on the collected spectrum. This feature is useful in
checking the system
The Peak Height, First Vector Pixel and Dark Level refer to the instantaneous readings for
those parameters.
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
The
Absorbance
page (Figure 5-8) presents the Absorbance spectrum and reports the
concentration of H

S
.
The range can be edited on the
Config
panel (Section 4.8).
