System Description
ProStar 363 Fluorescence Detector 19
Rear Panel
A complete description of the rear panel connectors and their
functions is found in the Installation section.
Flow Cell
The flow cell is located on the right hand side of the detector.
(See Figure 9.)
Figure 9 Flow Cell Connection
Connection to the flow cell is made though the front of the
instrument behind the door. The flow cell provides a path for
light to enter from the excitation monochromator and pass
directly through to the monitor detector. There is also a slit in the
flow cell which allows the fluorescent light to exit the flow cell and
enter the emission monochromator. Flow through the flow cell is
from the bottom to the top in order to minimize the likelihood that
bubbles could be trapped in the flow cell. Also, a back pressure
restrictor should be put on the end of the waste line to prevent
bubble formation.
