Laser Induced Fluorescence Detection
Installation
6
If the filter(s) are removed from a channel, re-install the beam blocker in its place to protect the
photomultiplier tube.
NOTE
If there is no arrow on the edge of the filter you are using, look at both sides of the filter and
determine which side has the more reflective surface. (Typically the more reflective side also has a
wide edge rim that extends beyond the filter surface). The filter should be installed with the more
reflective side facing the light source (the laser). In the LIF detector, laser light comes from the center
of the filter housing. So if you are holding the housing in the proper orientation, install a filter with
the arrow and/or reflective side with the wider rim pointing up (toward the filter housing).
If a filter is installed incorrectly, it will work but its performance may not be optimal.
