4.4.3 Leakage from the flow cell
It is important to check for any liquid leakage from the flow cell
unit prior to analysis. If a leak is found, stop the pump
immediately and remove the flow cell unit. Take the following
procedure to remedy the leak.
Inlet tube
Setscrew 2
Setscrew 1
Outlet tube
Fig. 4-14 Inlet and Outlet Tube
(1) Supply liquid using the pump, and check that liquid comes
out of the outlet tube of the flow cell.
(2) If liquid does not come out of the tube, it indicates the tube
is clogged. Replace the outlet tube with a new one.
(3) If a leakage occurs though liquid comes out of the tube
normally, setscrew tightening may be slightly inadequate.
Retighten setscrew 1 lightly (about 10 to 20
°
) with a wrench
or setscrew 2 lightly (about 10 to 20
°
) manually.
(4) Wipe up any liquid spilt on the outside of the flow cell.
(5) Before returning the flow cell unit into position, supply liquid
with the pump and make sure there is no more leakage.
NOTE
: It is important that the OUTLET tube of the flow cell be
checked first for clogging. If the upper setscrew is
judged to be loose and is retightened with the wrench
without checking the OUTLET tube, then the flow cell
may be damaged or broken.
NOTE
: If leakage is found in the sample compartment, wipe up
the liquid thoroughly and then clean with a cloth
moistened with water.
