7.3.2 Replacing the Flow Cell

Observe the following when removing or installing a flow cell:
Warning:

• Observe the precautionary statements in section 7.1 (→ page 107).
• If no flow cell is installed, the lamp turns off automatically.
• No tools are required to remove and install a flow cell.
• The contacts for the flow cell identification chip and the temperature control are located
on the rear of the flow cell. To ensure proper functionality, be careful not to touch the
sensitive electronics. If liquid comes into contact with the electronics, dry it immediately.
• Capillary connections between the column and flow cell should be as short as possible to
avoid peak broadening effects due to excessive dead volume.
The backpressure on the flow cell must not exceed 20 bar (analytical flow cell) or 40 bar
•
(micro flow cell). Do not connect any capillaries or instruments to the flow cell out line
as this might generate a higher backpressure. Even if the pressure exceeds the upper limit
for a very short time only, the flow cell may be permanently damaged. If it is required to
connect a valve at the flow cell outlet, the valve may only be switched while the flow is
stopped. When switching valves while the flow is turned on, pressure peaks may occur
and destroy the flow cell. Thermo Fisher Scientific recommends using a capillary or tube
with an internal diameter of at least 0.5 mm at the flow cell out line.,
The following flow cells are available for the detector:

Flow cells can become extremely hot during operation. To avoid
possible injury, allow sufficient time for the flow cell to cool down
before replacing the cell.

refroidir pendant une période suffisamment longue.
