4.5.1 Inserting the flow cell with fiber optics
KNAUER fiber optic cables are extremely robust. Nevertheless fiber optic
cables are sensitive to bending. The minimum bending radius is 100 mm
(short term: 70 mm).
Observe the following regarding the use of fiber optics:
UV light will cause the fiber optic to become blind with time (solariza-
tion), making them no longer suitable for use.
Do not touch the ends of the fiber optic with your fingers, as this could
falsify the measurement.
Handle the fiber optic with care, avoid impacts or hard actions.
Move the fiber optic carefully without using pressure or bending it.
The flow cells with fiber optics are connected via an adapter.
No flow cell or test cell is installed.
Screw-type cap fittings for the fiber optics
Eye injury
Irritation of retina through UV light. High-energy UV light can leak out
from the flow cell or the fiber optic connectors.
Switch off the detector or the lamps.
Note:
Other optical parts should never be touched without wearing glo-
ves because otherwise contaminations may reduce light intensity. Conta-
minated parts may be cleaned with a soft cloth and isopropanol.
