Flushing the detector
Caution:
41369 kPa (413.69 bar, 6000 psi) pressure limitation of the flow
cell.
To flush the detector:
1.
Stop the solvent flow to vent the system:
a.
From the console, select Binary Solvent Manager in the system tree.
Warning:
pressurized, liquid CO
displacement of oxygen within the confines of the laboratory space,
stop the solvent flow, and vent the system pressure before you
attempt flush the flow cell.
b.
Enter zero flow in the composition field or press the Stop Flow icon
and enter a flow rate of zero. The system will vent to atmospheric
pressure through the vent valve in the ACQUITY UPC
Convergence Manager.
2.
Remove the column from the system.
3.
Flush the system to waste with nonhazardous solvent at a rate of 1.0
ml/minute for 10 minutes.
4.
Flush the system with 100% methanol for 10 minutes.
Maintaining the leak sensor
A leak sensor in the drip tray continuously monitors the detector for leaks.
The sensor stops system flow when it detects accumulated, leaked liquid in its
surrounding reservoir, and an error message describing the problem appears
in the console.
To avoid damaging the detector, do not exceed the
