Using the Module
Installing Valve Heads
Install the Valve Head and Connect Capillaries
For bio-inert modules use bio-inert parts only!
For 1290 Infinity II Bio LC modules, use bio / bio-compatible parts only.
Do not mix parts between 1260 Infinity II Bio-Inert LC modules and 1290 Infinity II Bio LC modules.
CAUTION
The valve actuator contains sensitive optical parts, which need to be protected
from dust and other pollution. Pollution of these parts can impair the accurate
selection of valve ports and therefore bias measurement results.
Always install a valve head for operation and storage. For protecting the
actuator, a dummy valve head can be used instead of a functional valve. Do
not touch parts inside the actuator.
CAUTION
Column Damage or Bias Measurement Results
Switching the valve to a wrong position can damage the column or bias
measurement results.
Fit the lobe to the groove to make sure the valve is switched to the correct
position.
