BlueShadow Detector 50D Instructions V7659

8.4 Replacing the flow cell

UV light will cause the flow cells to become blind with time (solarization),

making them no longer suitable for use .

The device has been switched off .

The power plug has been pulled .

The capillaries have been removed .

Process

Figure

Remove capillaries at the inlet

and outlet

of the flow

cell .

Unscrew the knurled-head

screws

of the cover plate

. Hold the flow cell securely

with your hand during this

procedure .

Pull out the slide with the flow

cell

towards the front .

Remove the flow cell upward .

Insert new flow cell from ab-

ove into the flow cell holder .

Keep holding the flow cell .

Push the flow cell holder

against the detector again .

Screw the knurled-head

screws back into the cover

plate

and tighten .

Fig. 18

Replacing the flow cell

The flow cell is assembled .
