Setting Up an Analytical and Preparative System

Setting up a preparative system
The process of setting up a preparative system is very similar to that for 
setting up the analytical system, but since the Automated Purification 
software is installed on the preparative system, it is able to determine the 
current instrument configuration and show a warning if the system does not 
match the instrument configuration.
1 In the Chemstation Method and Run Control view, open the Purification menu 
and select Systems.
The Setup Systems Parameters dialog box is displayed. The preparative 
system parameters are displayed in the right panel; the analytical system 
parameters are displayed in the left panel. These instructions are for the 
preparative system parameters in the right panel.
2 Click Add System and provide a name.
You can also clone an existing preparative system.
3 In the Pumps & Detectors tab:
• The settings are based on the available modules in the current 
instrument configuration. This is either a preparative-only or a 
combined analytical and preparative instrument.
• In the Pumps section, if there is more than one pump in the instrument, 
select your preparative pump for the main flow. Specify the pump 
channels for organic solvent and water for the selected pump. The 
preparative flow rate needs to be set according to your planned 
preparative runs. The preparative flow rate can be set as calculated from 
the analytical flow (of the selected analytical system in the left panel) 
considering the different column geometry in order to maintain same 
chromatographic conditions. If a second pump is configured in the 
instrument and an MSD or auxiliary detector is set up for the 
preparative system, you can also select a make-up pump, which delivers 
the flow to the MSD or auxiliary detector. 
Make sure that you choose a system name that helps you and other operators identify 
your system among others; for example, use the laboratory and instrument name/number 
and key operating parameters within the system name.
