6.4 Optimizing the Spectrometer Energy Level

Optimization of the Spectrometer Energy Level is periodically required to maintain a sufficient

signal to noise ratio on the spectrometer output signal as the spectral output signal from the

spectrometer will deteriorate over time. The normal causes of this deterioration are:

•

Degrading Anti-Solarant Solution

•

Aging UV Source Lamp (output reduces over time)

•

Dirty cell windows

•

Dirty optics

•

Optical fibre problem

For convenience, the energy level of the spectrometer output signal is gauged by observing

the peak level as displayed on the Spectrum panel of analyzer or the Analysis/Spectrum

page on the Web GUI under zero gas conditions. When optimizing the spectrometer signal,

the normal target value for the peak value is 32000 counts (+/- 500).

The spectrometer energy level can be optimized manually (for special cases), or

automatically as a function of the analyzer. The automatic function will always target 32000

counts.

Before proceeding with either procedure below, ensure that the analyzer is

‘Off Line’ and is being purged with zero gas.

6.4.1 Automated Optimization

a) Place the analyzer in back purge mode. This can be done by accessing the

Back Purge

field on the

Analysis 1

panel and pressing

Enter

to place an

in the box.

b) Access the

Spectrum

panel, navigate to the

Optimize Integ Time

field and press

Ente

c) Return to the

Analysis 1

Panel.

d) Request a Manual Zero by navigating to the “Manual Zero” field and pressing Enter.

e) Remove the Zero mode by accessing the

Sample

field and then pressing Enter to put an

x in the box, thus allowing the analyzer to return to normal sampling.

6.4.2 Manual Optimization

a) Place the analyzer in Zero mode by accessing the

Analysis 1

panel, place an X in the

Back Purge

field and pressing Enter.

b) Access the

Spectrum

panel.

c) If the peak level is between 25,000 and 32,000 then no adjustment is required at this

time.

d) If adjustment is necessary, optimize the peak signal height to 32,000 counts. Navigate to

the “

Set Integ Time

” field and press

Enter

to display the

Integration Period

dialog box.
