Before starting the system, make sure that your epsilon chromatograph and its software have been installed as specified in the INSTALLATION section. All peripheral equipment such as pump, external detectors, heaters, etc. should be turned on and connected as appropriate. Allow the instruments to complete their self checks before starting ChromGraph Control software.
Start ChromGraph Control with either a desktop shortcut icon or the Windows Start Menu:
Alternatively, you can start Control (or bring it to the forefront if it was minimized) with the 'Run CONTROL' option in the Data drop-down menu of ChromGraph Report:
One of two things will happen at this point. If everything is connected properly, a picture of a chromatograph will appear. But if the computer cable is plugged into the wrong communications port, or is unplugged, the EQUIPMENT OPTIONS box will appear.
To get to the options box if it does not come up, take the EQUIPMENT OPTIONS alternative in the Data menu:
The following sections should be filled out:
COM Port: Com1, Com2, Com3, or Com4 should be depressed, depending on which port you've used when connecting the epsilon system to the computer. (Click to revhref="/manuals/LC_epsilonhref="index#installation">INSTALLATION section.)
Power: Unchecked = 60 Hz (USA). Checked = 50 Hz.
Equipment Used: Click the epsilon radio button.
Press the OK button next. The Equipment Options screen should come back with entries in the 'BAS ROM Versions' section, indicating that the software is communicating with the epsilon system. Press OK again and this screen will be replaced by a picture of a chromatograph.
SETUP OPTIONS allows you to set some user preferences. This screen is reached as follows:
Check the options that you wish to use:
SMART MOUSE positioning puts the mouse cursor on the next OK >> or << OK button when you switch among the Method screens . It is an aid to rapidly scrolling through the Method.
AUTO-BACKUP Method saves a reference Method with each series of runs. Most users do not wish to store all these extra methods, so we recommend this feature only for those in regulated environments where every run must be documented.
The remaining options define how information is transferred from the BASi Sample Sentinel autosampler when importing sample-identifying information for attachment to the run data. Click here for a discussion of this advanced topic.
You can exit by clicking the X-button at the top right of the screen, or by taking the QUIT option in the DATA drop-down menu. In either case you'll be asked about saving certain items:
It's a good idea to check both items:
PRESENT METHOD FILE allows the current Method to be saved as temp.mth every time you exit, and therefore reloaded automatically at the next session. This temporary Method differs from your original Method in that it remembers the last run number and comes up ready to do the next run in the sequence.
INITIALIZATION FILE saves the equipment options, setup options, screen colors and sizes, and default data directories so they will automatically go into effect at the next session. Any time you change these options during a session you must decide whether to make the changes permanent. Exit and save the initialization file to make them permanent. Exit and do not save the initialization file to forget the changes. If you don't want to exit, you can save the initialization file through an option under the Data drop-down menu:
