Installation
15
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.
Prerequisites
No flow cell or test cell is installed.
Auxiliary Material
Screw-type cap fittings for the fiber optics
Eye injury
Irritation of retina through UV light. Concentrated UV light can leak out
from the flow cell or the fiber optic connectors.
Switch off the device or the lamps.
Note:
Fiber optical connectors, like all other optical parts, should never be
touched without wearing gloves because otherwise contaminations may
reduce light intensity. Contaminated parts may be cleaned with a soft cloth
and isopropanol.
Next Steps
Connect the capillaries.
Connecting the Capillaries
Capillaries connect the detector with the column and guide liquids. For the
flow cell connectors, we recommend PEEK capillaries and PEEK fittings.
Prerequisites
The flow cell was inserted.
Screw-type cap fittings and cap fittings were removed.
Note:
The KNAUER LightGuide flow cell cartridges have unisex input and
output connections.
Component defect
Damage to the ports caused by strongly tightened fittings.
Use 5 Nm torque for stainless steel fittings.
Use 0.5 Nm torque for PEEK fittings.
