Instrument Setup – S 2550 Detector
The detector S 2550 supports the general detector settings described on
page 91.
Fig. 143 Detector S 2550 setup window
Used Channel
Check the box(es) to turn the acquisition for the selected channel(s) on.
Only channels that have been selected in the instrument configuration of
the detector are available. If the box is not selected, no data will be
acquired and no time program will be executed for this channel. As many
channels are activated (at least one) as many wavelength columns
appear in the spreadsheet below.
The wavelength table is a spreadsheet to enter your time (detector)
program. In the first row (at time 0.00 min), enter the initial wavelength(s)
in nm. The editing principle including programming the digital outs is the
same as for the time (gradient) program, described in the chapter
Instrument Setup – Pumps, Pump Program.
Autozero at WL change
Check this option if you wish the signal to be zeroed at the moment the
wavelength is changed (to define the current signal as the baseline).
[Action] at the end of run
The detector S 2550 allows not only to switch off the lamp at the end of
run, but also to switch the device into Standby.
You should switch on the lamp either manually or from the direct
control window before you start the next working session. After
power up, allow 20 minutes for the lamp to stabilize before running
samples that may require sensitive measurements.
Scan, nm [Range xxx – yyy nm]
This section allows you to specify the scan spectral interval, in nm.
Start
Enter the start wavelength for the scan in nm.
End
Enter the end wavelength for the scan in nm.
Acquire 3D data
You have access to this selection field only with the PDA option. The
displayed range depending on the detector type and the installed lamps
will only be updated, if you open that window online. The Advanced…
button becomes accessible if the Acquire 3D data check mark is set.
