Installation Of Chromgraph Software

ChromGraph is a sophisticated set of programs for the control of BASi instruments and the analysis of data generated by Liquid and Gas Chromatographs. The software runs in the Windows environment, thus providing all the flexibility and multitasking inherent in this operating system.



ChromGraph will run on almost any modern computer. The minimum specifications call for a Pentium®-class CPU with a 166 MHz clock speed. There should be at least 32 MB RAM and the operating system should be Windows 95 or most newer version of Windows.

ChromGraph comes as two sister programs, ChromGraph Control and ChromGraph Report. Control sets the instrument parameters and oversees the collection and storage of data. Report processes the data after it has been collected. The two programs can run independently or can be configured so Control automatically passes the data to Report for immediate processing.

If you purchased ChromGraph in a package that included a computer, the software will already be installed. If you are doing your own installation, follow the instructions for installing ChromGraph software and for setting the power-management options of your computer.






  1. Double-click on the 'My Computer' icon on the desktop, then double-click on the CD-ROM icon (usually drive 'D'). Double-click on the setup icon for your operating system (either the Windows 9x/ME family, Windows NT4, or the Windows 2000/XP family). NOTE: You may have to hold the mouse over the icons to see the full name of the file, which will indicate the operating system, the version of ChromGraph, and the word 'setup'.


  2. You should accept all the default installation options as they are presented to you.


  3. Shortcuts to the BASi programs and the on-line manual will be installed in the Start Menu, under Programs/ChromGraph. Icon shortcuts for the programs and the manual will be installed to the Windows desktop.


  4. The setup program will ask whether you wish to restart the computer. You need not restart immediately, but must restart before running ChromGraph Control software.


  5. If you ever wish to uninstall ChromGraph software, go to the Windows Control Panel (Start, Settings, Control Panel), double-click on the 'Add/Remove Programs' icon, highlight 'ChromGraph' in the list of programs, and press the Add/Remove button.





Windows computers usually are set to reduce power to hard drives and monitors after a certain amount of inactivity. This could prevent ChromGraph from saving the chromatography data to disk after long runs, or during overnight operation with an autosampler. We therefore recommend that you turn off any power-saving features of your computer. The procedure that follows is easy to do and works for most computers. In some cases, however, you must disable power-saving features in the computer's BIOS ” consult the computer manufacturer if this is the case.


  1. Right-click on the desktop and choose 'Properties'.


  2. Click on the 'Screen Saver' tab.


  3. Click on the 'Power' button.


  4. Change each setting to 'Never'.


  5. Use the 'Save As' button to save this scheme under the default name.


  6. Close all the screens with the 'OK' button.
