Clean the Max-Light Cartridge Cell

When

Tools required

Qty.	p/n	Description
1		Alcohol (Iso-propanol or Ethanol)
1		Lens tissue or Q-tips ®
1	5190-0530	Cell cleaning solvent

Flush the flow cell with the alcohol for some time.
Remove the cell from the cartridge holder (see Replace the Max-Light Cartridge Cell).
Carefully clean the light inlet and outlet of the cell using lens tissue or Q-tips^® with alcohol.

NOTE
If Q-tips^® are used, ensure that no cotton fluff remains at the inlet or outlet.

NOTE
Do not touch the light inlet and outlet of the cell with your fingers. This will add a layer of contamination on the window and reduce the light throughput.
Flush the flow cell with water and repeat the Intensity Test and or Cell Test.
If the cleaning with the alcohol did not improve the results, the flow cell might be cleaned with cleaning fluid (PN 5190-0530). Use a concentration of 0.5 – 2 v/v % (cleaning fluid/water). Use a syringe to fill the flow cell with cleaning fluid.
The following cleaning protocols are recommended:
- Maximum 3 hours at 25 – 30 °C or
- 30 – 40 min at 30 – 35 °C.
NOTE
The optimal concentration depends on the water quality, the contamination, the temperature, and other factors. The use of demineralized water may improve the cleaning characteristics.
Flush the flow cell with water and repeat the Intensity Test and or Cell Test.
If tests fail again, the flow cell might be replaced if the chromatographic performance cannot be accepted.
