Inspecting, cleaning, and replacing damaged flow cell
components
To inspect or clean the parts of the flow cell or to replace damaged parts of the flow
cell such as the lenses, exit window, or gaskets, follow this procedure and then rebuild
the flow cell.
Recommendation:
Replace the clear plastic gaskets each time you inspect and
clean the flow cell.
To inspect and clean the flow cell:
1. Inspect each part of the removed flow cell for dirt.
2. Using ethanol or methanol, clean the contaminated part, and dry it under a
stream of nitrogen.
3. Using the Flow Cell Rebuild Kit, replace any flow cell parts that are scratched,
burred, damaged, or do not come clean using nitrogen.
4. Rebuild the flow cell by following the procedure in the next section.
4.4.3.5
Rebuilding the flow cell
After cleaning or replacing other flow cell parts, rebuild the flow cell.
Notice:
To prevent contamination, wear clean, chemical-resistant, powder-free
gloves when disassembling, inspecting, cleaning, or replacing parts within the
Waters TaperSlit Flow Cell or when removing or replacing the flow cell within its
assembly. Work on a clean flat surface, such as a lint-free cloth or similar
surface.
