-
Flush the flow cell with the alcohol for some time.
-
Remove the cell from the cartridge holder (see Substituir a célula cartucho Max-Light).
-
Carefully clean the light inlet and outlet of the cell using lens tissue or Q-tips® with alcohol.
NOTA
If Q-tips® are used, ensure that no cotton fluff remains at the inlet or outlet.
NOTA
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.
NOTA
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.
