Preparations
1. Flush the flow cell with a highly pure solvent that is miscible with
isopropanol, such as LC/MS-grade acetonitrile or methanol.
Make sure that residual sample components, impurities from the
column, aggressive solvents or eluates with salt contents are
completely flushed out of the flow cell.
2.
If the UV lamp is turned on
Close the shutter in the light path before the flow cell.
-or-
Turn off the UV lamp.
3. Stop the pump flow to the flow cell.
Follow these steps
1. Unpack the components from the inject and flush kit. Remove the
protection cap from the Viper connector. Keep the packaging.
2. Screw the threaded end of the flushing adapter to the syringe.
3. Draw up highly pure isopropanol with the syringe through the Viper
adapter, for example 1.0 mL.
4. Disconnect the capillary from the flow cell inlet.
5. Connect the Viper adapter to the flow cell inlet.
6. Push the isopropanol in the syringe into the flow cell. Make sure that
no residual air in the syringe is pushed into the flow cell.
7. Disconnect the waste line from the flow cell outlet.
8. Disconnect the flushing adapter from the flow cell inlet.
9. Install the flow cell plugs to the flow cell inlet and flow cell outlet.
10. Unscrew the flushing adapter from the syringe.
11. Make sure that the adapter and the syringe are empty and dry.
12. Put the protection cap onto the Viper adapter.
13. Pack and store the components of the kit in their original packaging.
