2. Choose the system (chromatograph) associated with the
method. A method is created for a particular system. When
starting an acquisition, the name of the system that performs
the acquisition must be correct, since method access is
limited only to those methods associated with this system.
3. Once this field is completed, click on the Next button to
move to the second step of the method creation:

ProStar 363 Control Manual - 11 - 03-914947-26:.2
4. Enter the New Method Name in the first field. In the
Description field, enter information concerning the method
(optional).
5. Once these two fields have been completed, click on the OK
button. The new method is created and is opened with
default parameters in the Galaxie Chromatography Data
System. The next step is the definition of each of the method
sections.
The control section must be defined in order to start an
acquisition. In the following part of this guide, only the control
section for the Varian ProStar 363 Fluorescence Detector is
detailed. Other parameters such as Injection Volume, Vial
and Rack number may be necessary and are defined in the
acquisition section.

photomultiplier tube. Three choices are available: High,
Medium or Low. Generally, the higher the voltage is, the
greater is the sensitivity of the photomultiplier tube to light.

ProStar 363 Control Manual - 14 - 03-914947-26:.2
Select from the list the range of wavelengths (Emission
Bandwidth parameter) centered around the emission wavelength
that will be detected. Two choices are available: 15 or 30 nm.
Enter the Signal Offset value (from 0 to 1000 mV) that will be
added to the detector output signal to create a positive baseline
offset.
Check Shutdown lamp at sequence end to switch off the lamp, at
the end of acquisition (Quick Start and sequence).
Check Lock detector keyboard during runs to lock the detector
keyboard.
Program the evolution of the Excitation and Emission
wavelengths. The Excitation parameter is the wavelength of light
(from 200 to 850 nm) used to energize the molecules in the
column eluent. The Emission parameter is the target
fluorescence wavelength (from 250 to 900 nm) measured by the
PMT to generate the detector signal.
Check the Az parameter to zero the detector output at the
programmed step time.
Use the following buttons to edit the table:
