Disassembling and Cleaning of an Analytical 3 mm Flow
Cell
The 3 mm flow cells have a rod-shaped light guide.
1. Unscrew the fiber optical connector with a wrench.
2. Remove the PEEK shutter.
3. Get hold of the gasket holder with the light guide by grasping it with a
pair of tweezers, using the indentations on the outer side of the
gasket holder.
4. Push out the light guide and strip the PTFE sealing ring in order to
clean the lens.
5. Reassemble the cell in reverse order. Use a new PTFE sealing ring
after every disassembly to ensure the consistent operation of the flow
cell.
