3 Using the detector
Starting the detector
Starting the ACQUITY refractive index detector entails powering-on the
detector and each system module individually, as well as the ACQUITY
workstation. It also entails starting the operating software (Empower).
To start the detector:
1.
Power-on the workstation.
2.
Press the power switch on the top, left-hand side of the solvent manager
door, sample manager door, column manager (if included in the system),
and RI detector door.
Result:
The power and run LEDs change as follows:
•
Each system module's power LED shows green.
•
During initialization, each system module's status (or run) LED
flashes green.
•
After the modules are successfully powered-on, all LEDs show
steady green. The solvent manager's flow LED and the sample
manager's run LED remain unlit.
3.
Start Empower software.
You can monitor the ACQUITY console for messages and LED

indications.
4.
Flush all flowpaths of the detector including the Purge and Recycle
flowpaths.
For maximum sensitivity, use the same solvent to prime all solvent

Note that it can take several hours for the optics bench to stabilize at a new
temperature. Do not make a run until the temperature stabilizes. Changing
temperature causes baseline drift and can necessitate lamp reoptimization.
A low ambient temperature can prevent the detector's oven from
