Installing the LightPipe Flow Cell
 To install the LightPipe flow cell
1. If the photodiode mount is attached to the end of the LightPipe mounting assembly,
detach it as follows.
a. Using the 3/32 in. hex wrench (supplied), loosen and remove the two photodiode
mount retention screws (see Figure 20 on page 28 ).
b. Carefully pull the photodiode mount straight back and off the LightPipe mounting
assembly. Place the photodiode mount out of the way inside the detector housing or
on the benchtop.
2. Remove the protective end caps from the ends of the LightPipe flow cell.
3. Using the supplied fittings, attach the inlet tubing and the outlet tubing to the flow cell as
follows:
a. Connect the insulated red PEEK inlet tubing to the port in the bottom of the
flow cell.
b. Connect the blue PEEK outlet tubing to the port in the top of the flow cell.
