Introduction
LightPipe Flow Cell
4 Surveyor PDA Plus Detector Hardware Manual Thermo Scientific
Mobile phase enters the 10-mm LightPipe flow cell through a port in the bottom of the flow
cell and exits through a port in the front of the flow cell as shown in
Figure 4 . Directing the
flow upward helps prevent the entrapment of air bubbles.
Figure 4. Schematic of 10-mm LightPipe flow cell
Sensitive optical fibers are exposed at both ends of the flow cell (see Figure 5 ). Thermo Fisher
Scientific ships the LightPipe flow cell with end caps to protect these optical fibers (see
Figure 6 ). Do not remove the protective end caps until you install the LightPipe flow cell.
Replace the protective end caps for storage if you remove the LightPipe flow cell from the
detector.

CAUTION Do not touch the ends of the LightPipe flow cell. Doing so could damage the
sensitive optical fibers. If you must grasp the ends of the LightPipe flow cell, wear clean,
talc-free gloves.
