注記
All descriptions in this procedure are based on the default orientation of the cell (as it is manufactured). The heat exchanger/capillary and the cell body can be fixed mirror symmetrically to have both capillaries routed to the bottom or to the top (depending on the routing of the capillaries to the column).
注記
The fittings at the flow cell body are special types for low dead volumes and not compatible with other fittings. When retightening the fittings, make sure that they are carefully tightened (handtight plus 1/4 turn with a wrench). Otherwise damage of the flow cell body or blockage may result.
-
Identify the inlet and outlet capillaries.
-
Remove the outlet capillary.
-
To replace the inlet capillary, use a 4 mm wrench to open the fitting.
-
Unscrew the cell body from the heat exchanger.
-
Remove the heat exchanger from the clamp unit.
-
Use a small flat screw driver to carefully lift off the I.D. tag. Shown is the default orientation. See Note at the beginning of this section.
-
Carefully insert the I.D. tag into the new heat exchanger. Shown is the default orientation. See Note at the beginning of this section.
-
Fix the heat exchanger to the clamp unit.
-
Fix the flow cell body to the heat exchanger.
-
Fix the inlet capillary to the flow cell body handtight first. Then do a 1/4 turn with a 4 mm wrench.
-
After replacing the outlet capillary, fix it handtight first. Then do a 1/4 turn with a 4 mm wrench.
-
Check for a centered holder vs. hole. If required adjust with the holder screws.
-
Reconnect the capillaries, see フローセルの取り外し/取り付け.
-
Perform a leak test.
-
Insert the flow cell.
-
Close the doors.
-
波長ベリフィケーションテストまたはホルミウムテストを実行し、ランプが正しい位置に取り付けられていることを確認します。
