1 Unscrew the cell screw using a 4-mm hexagonal wrench.
2 Remove the SST rings using a pair of tweezers.
3 Use adhesive tape to remove the peek ring, the window and the gasket.
4 Repeat
step 1 through
otherwise they could be mixed !).
5 Pour isopropanol into the cell hole and wipe clean with a piece of lint-free cloth.
6 Clean the windows with ethanol or methanol. Dry it with a piece of lint-free cloth.
7 Hold the flow cell cassette horizontally and place gasket in position.
Ensure both cell holes can be seen through the holes of gasket.
8 Place the window on gasket.
9 Place the peek ring on the window.
10 Insert the conical springs. Make sure the conical springs point towards the window.
Otherwise tightening the cell screw might break the window.
11 Screw the cell screw into the flow cell and tighten the screw.
12 Repeat the procedure for the other cell side.
• Reconnect the capillaries, see
"Zero-Order Calibration"
on page 61 to check the correct positioning of the flow cell.
