The HDR-DAD Cluster includes two G4212A/B DADs, one with a long flow cell (for example, 60 mm), the other with a short flow cell (for example, 10 mm). The signals from the two DADs are combined to produce a high-dynamic-range signal.
The recommended connections for the HDR-DAD Cluster are set up as follows:
The DAD in the HDR-DAD Cluster with the long flow cell is plumbed first in the flow path. The capillary between the first DAD and the second DAD in the HDR-DAD Cluster determines the delay volume (default 11 µL).
Typically, the DAD in the HDR-DAD Cluster with the short flow cell is connected to the instrument so that it has the same network address as the instrument.
The other DAD in the HDR-DAD Cluster (typically, the one with the long flow cell) has a separate, additional network connection.
Start the configuration by providing an IP address or Hostname as primary connection to the instrument.
If two G4212A/B DADs are detected, the cluster configuration dialog box is displayed.
Select the two DADs to include in the HDR-DAD Cluster and click .
The HDR-DAD Cluster Configuration dialog box is displayed.
Select the DAD that does not have the IP address of the main instrument connection and click . In the recommended setup, this is the DAD with the long flow cell.
In the configuration dialog box, click and provide the IP address of the DAD.
When you close the configuration dialog boxes, the connection address is shown in the Additional Connection column of the table.
Provide any additional information in the HDR-DAD Cluster Configuration dialog box (non-standard delay volume, linked pump) and click OK to complete the configuration.
The delay volume should be corrected after carrying out a manual delay volume calibration, see the HDR Solution User Guide for details. |
