Starting the nanoACQUITY UPLC Console from

MassLynx

The nanoACQUITY UPLC Console is a software application that replaces the
keypads and small display screens traditionally found on the fronts of system
instruments. It provides a convenient way to configure settings, monitor
performance, run diagnostic tests, and maintain the system.

To start the nanoACQUITY UPLC Console from MassLynx:

1.

In the MassLynx window, click Inlet Method.

2.

Click the ACQUITY Additional Status tab.

ACQUITY Additional Status tab:

3.

Click Display console

.

Result:

The nanoACQUITY UPLC Console window appears.
