Installation
Process
1. Set up the package in such a way that you can read the label. Using the
utility knife, cut the adhesive tape and open the packaging.
2. Remove the foam insert. Take out the accessory kit and the manual.
3. Open the accessory kit and check the scope of delivery. In case any parts
are missing, contact the Technical Support.
4. Clasp the device from below, lift it out of the packaging and place it on
its feet. Do not hold onto the front cover.
5. Check the device for signs of damage that occurred during transport. In
case you notice any damage, contact the Technical Support.
6. Place the device in its site of operation and remove protective foil.
Next steps
Store packaging and keep the included packing list for repeat orders.
Note:
The test cell is used during operation qualifications and must be
stored.
Inserting the Flow Cell
Before taking a flow cell filled with solvent into operation, please make cer-
tain that the used eluent is miscible with that one used previously. Other-
wise purge the flow cell with a medium miscible with both the eluents.
Prerequisites
No flow cell or test cell is installed.
The device is switched off.
Note:
Pay attention to the compatibility of the flow cells.
Practical Tip:
Unscrew the capillary for easier handling.
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.
Performance decrease
Any components in the light path like fiber optic ends become contami-
nated, if being touched with the fingers.
Avoid touching the ends without gloves.
Use alcohol and a cotton bud for cleaning.
Next Steps
Connect the capillaries.
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.
