Figure 34 Dismantling or assembling the flowcell 

3.

 

When the flowcell is dismantled, use a lens tissue and a suitable solvent, for example 

heptane, to clean the flowcell. 
 

 

 

WARNING 

Do not use acid to clean the windows, as toxic fumes will be given off. 

Take care not to crease the wedged PTFE spacer during cleaning as this 

may reduce its effectiveness at suppressing interference fringes, and may 

also alter the pathlength. 

4.

 

Refit the parts of the cell in the following order: 

–

 

The neoprene gasket 

–

 

The back window 

–

 

The former 

–

 

The PTFE spacer (with the thin edge of the wedge towards the top of the cell) 

–

 

The front window 

–

 

The PTFE gasket 

5.

 

Align the two holes in the PTFE gasket with the two holes at the ends of the channels in 

the front window.
