To plumb the detector
Recommendation:
PDA/eλPDA Detector from the system tree and click
extinguish the lamp.
1. Open the detector's front door, and install the flow cell assembly, holding
it squarely with respect to the opening and then inserting it slowly so
that the guides on the front part of the flow cell flange engage the rails
in the sample cell compartment.
2. After the flange and rails are engaged, continue inserting the flow cell
until the dowel pins on the detector engage the corresponding holes on
the cell holder.
3. Continue to insert the flow cell until the three thumbscrews align with
their holes in the bulkhead.
