Figure 60 Disassembling or assembling the flow cell
3.
When the flow cell is disassembled, use a lens tissue and a suitable solvent, for example
heptane, to clean the flow cell.
CAUTION
DO NOT use paper products such as standard laboratory tissues, as these
are likely to scratch the ZnSe windows. 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.
Reassemble the flow cell in the following order:
–
The former
–
The rubber gasket
–
The back window (smooth on both faces and has no holes in it)
–
The PTFE spacer (wedged, with thicker end at bottom of cell)
–
The front window (engraved on one face and has two holes in it)
–
The PTFE gasket (refer to Step 5)
–
The front of the cell (refer to Step 6)
5.
Align the two holes in the PTFE gasket with the two holes in the front window.
6.
Lay the front of the cell on top of the gasket.
