Operation advice
•
Elution of a sample–free area on the plate cleans the system from residues of the
last elution. In this manner you can also measure the plate background for later
correction
•
The positioning table must be wiped off before you put a plate or foil on it.
•
Capillaries to the detector system should be kept as short as possible
•
Increasing the flow rate results in faster elution time but larger elution volume and
a rise of pressure
•
Caution: It is not recommended to leave the ports of the valve unconnected
without protecting them from dust. Please use the included taps or similar parts to
protect the ports
Check chapter Maintenance and Service for a trouble-free handling of the instrument.
