Note:
The divert valve has a total of seven ports, one of which connects to the RDa source via
the probe capillary assembly. The divert valve is fully automated to send the LC flow to either the
source or waste. The flow state function selects the position of the LC flow. When the fluidics are
operating, the flow state is set to waste as the LC flow is diverted to waste.
1.4 ACQUITY RDa Detector leak sensors
A leak sensor in the instrument’s drip tray continuously monitors for liquid leaks. If a leak occurs,
the instrument detects it and the software stops the LC flow to prevent the loss of sample and
any damage to the system. At the same time, the software displays an error message alerting
you that a leak has developed. Check that the divert valve connections from the sample bottles at
the front of the machine are not leaking. If they are, tighten the nuts to stop the leak, or replace
the leaking fitting.
