Description

Enable Virtual Mode

Verify that the check box is cleared.

Select only if you want to simulate autosampler control without the VAS being physically connected to the Chromeleon Server PC (see Virtual Mode).

Device Type

(Available only in Virtual Mode.) You can select the autosampler type in virtual mode if no autosampler is connected. If an autosampler is connected, Chromeleon detects the module type automatically as soon as you have entered the module address (see below).

Module Address

Select the module address of the autosampler. Click Browse to open the Device List dialog box, which lists the addresses and serial numbers of all autosamplers that are connected via a USB connection. Double-click to select the autosampler that you want to use. The module address is automatically entered in the Module Address field.

Charger

Select this check box if a Vanquish Charger (VCH) is installed and connected. Select a COM port from the list and click Try Connect to establish communication to Chromeleon.

Note:

It is important that the Charger is on and connected before the sampler configuration dialog box is opened to ensure that the related virtual COM port is displayed in the list of available COM ports.

Pump Link

Flow through sampler is delivered by pump

If the sampler is used in combination with the Vanquish Quaternary pump or any other pump supporting pump stroke synchronization, link the VAS to the pump which provides a stroke synchronization signal to support LPG pump stroke synchronization of the sampling and injection process. Select the pump from the list.
