2. Solvent selector
3. Diverter and Fraction collector
4. Column heater
5. Manual Injector
Column Valve modules Options
Holds up to 4 Automated valves
Hold up to 4 manual valves in front panels (any kind)
One or two independent column heater blocks
Vapor sensor
Holds 6 analytical or 2 prep (2 in) columns
Solvent selector
Column selector
System with ternary pump
Diverter and Fraction collector valves
Control and Operation
Front panel control
• Configure new valves
• Set all valve positions
• Set column temperature
• Set vapor response
• Divide valves between two different instruments
CANNOT TIME PROGRAM VALVE POSITIONS FROM FRONT PANEL
Control and Operation
BCD control
• Time program valves from an external computer via contact closures• BCD always built in
Computer control basics
• RS 422/485 serial communications– This is different than the ProStar communications line and cannot share the same line
• Independent of Galaxie - works with any other software• Runs with Galaxie through AutoLink
Computer control capabilities
• Time program valve movements through methods• Manually control valve movements through the computer• Control all other front panel operations• Preserve solvent compatibility during operations
Software control of the CVM
Prevents solvent incompatibility
Checking solvent compatibility
Documentation of columns and solvents
Problems
•Valve Status problem
•Valve leaks
•Communications problems
•Heater does not heat
