AZURA® Conductivity Monitor CM 2.1S Instructions, V6710
Note:
Never use organic solvents for flushing after working with buffers.
Always flush with water first. In addition, always rinse with water after each
rinsing with organic rinsing solutions - including aqueous mixtures. Sub-
sequent dry blowing with oil-free compressed air further increases the
cleaning effect.
Pump or syringe
Process
1.
Using the pump or syringe, flush generously with flushing solution.
2.
Blow the capillary free with compressed air.
Performance decrease
For the drying step, oil drops from compressed air can contami-
nate the flow cell which may result in performance decrease.
Î
Do not use compressed air for drying.
Check the system pressure and sensitivity.
8.4 Replacing the CM flow cell
The device has been switched off.
The power plug has been pulled.
The CM flow cell has been flushed (see chapter 8.3).
The capillary connections have been disconnected from the
FPLC/HPLC sys tem.
Hexagon wrench, size 1.5 mm
Note:
Make sure that you loosen the outer screws. Loosening the inner
screws opens the flow cell.
