To prevent damage or premature wear to the pump and internal
valves, clean solvent should be used. The solvent should not
contain any dissolved solids.
Note
An optional, manual solvent selection valve kit may be added to
provide inlets for two A solvents and two B solvents. If using the
optional valve kit, connect the kit and solvent lines according to the
instruction sheet.
Accessory package P/N 60-5239-012 includes pieces to
complete the solvent inlet connections.
1. Locate a Solvent Inlet Filter Assembly (P/N 60-5234-193)
in the accessory package. Connect the tubing end to the A
Solvent inlet. Thread the nut into the Solvent A Inlet and
finger-tighten.
2. Connect the second Solvent Inlet Filter assembly to the B
Solvent inlet.
3. Insert the filter end of each solvent inlet filter assembly
into their respective solvent containers.
4. The accessory package includes labels to easily identify the
inlet lines. Apply the A and B labels to the solvent lines
above the solvent container openings.
If solvent containers are reused, particulate matter can
accumulate in the container. Containers should be thoroughly
cleaned before each refill. Failure to clean the containers may
result in damage to the solvent selection valve and internal
components.
Note
When using higher-density solvents such as dichloromethane
(DCM), place the solvent container level with or above the
CombiFlash Rf system. Placing solvent containers below the level
of the system can contribute to decreased flow due to the high
vapor pressure of DCM. This problem becomes more pronounced
as the ambient temperature increases.
