ProStar 335 Photodiode Array Detector Control Manual - 30 -
Select the Slit Width in the list. The allowable values are 1, 2, 4, 8
and 16 nm.
In the Sequence end scrolling list, select Hold to maintain the run
end wavelength and attenuation values or Reset to re-initialize
the detector at the end of the Galaxie run.
Check the Lamp Off at the end sequence to enable this option.
When this option is enable the Varian Prostar 335 lamps will be
turned off at the end of a Galaxie sequence.
Signal control parameter group:
Select from the list the Bunch Rate of the detector. With
increased bunch rates, less disk space is required to store the
data.
With decreased bunch rates, more data is collected. Bunch rate
should be set appropriately for the narrowest peak of interest in
the chromatogram.
Enter the Analog Output Time Constant in the corresponding
field. This parameter specifies the degree of electronic noise
filtering applied to the analog outputs. It affects only the recorder
and data system analog outputs from the detector module, and
does not affect the data sent to the Galaxie Chromatography
Data System.
Enter the Noise Monitor Length in the corresponding field. This
parameter sets the number of points collected during the
monitoring period and is used to calculate the baseline noise.
