Installing and Controlling Third-Party Devices
Waters Alliance 2790/2795 HPLC Modules: Installation

 

Device Type:

HPLC module

Device Driver:

Waters: 2790/2795 Separation Module

The driver was tested with firmware version 2.00

Hardware Options
Supported:

2790/2795 or 2790/2795 XE including the following devices:

  • Pump: Quaternary gradient pump (0.05 to 5.00 mL/min)

  • Injector (1200 vials, 4 carousels)

  • Sample Temperature Control (XE version: 4-40°C)

  • Column heater (XE version: 20-60°C)

  • In-Line Vacuum Degasser with relative pressure reducer (2790: 4-channel degasser with 1 channel reserved for solvent purging; 2795: 5-channel degasser with 1 channel reserved for solvent purging)

  • Bar code reader (option)

Alliance eSeries:

The Alliance e2795 Separation Module is equipped with a GPIB communication interface which allows control of the system using the 2790/2795 driver.

Restrictions:

  • All parameters related to the flow, temperature, and event control are downloaded to the instrument as one single block. As a result, most properties cannot be changed at negative retention times.

  • The Waters Alliance 2790/2795 HPLC Modules can be controlled only after they have been completely initialized.

  • If you condition the column via the associated dialog on the device, it may happen that the PGM fFile cannot be executed.

  • This Waters device cannot connect to a NI-488.2 driver version 15.0 or later. You must use a NI-488.2 driver with software version ≤ v.14.0).

 

What is required?

License:

Timebase Class 2

Connection:

The following cable is required:

GPIB cable (Dionex part no.: 5919.0013; for more information refer to  GPIB IEEE 488 Bus Cable)

 Tip: 

You cannot connect the Waters Alliance 2790/2795 HPLC Modules to a UCI Universal Chromatography Interface because the UCI does not provide a GPIB connector.

Hardware
Prerequisites:

GPIB inteface card or GPIB/USB adapter

 Tips:  

The Waters BusLAC/ETM card cannot be used with Chromeleon.

Dionex advises against using Waters devices and Agilent HP 1100 Systems on the same GPIB card.

Software
Prerequisites:

VISA library (≤ version 14.0)

Control Panel:

Waters2790_996PDA.pan

Hardware Installation

 Caution:

When connecting several devices or systems via GPIB, connect them in series (not in a star structure) and turn all devices on. Otherwise, communication problems may occur.

  1. First, install Chromeleon software, and then connect the instrument using the GPIB IEEE 488 bus cable from Dionex.

  2. Make the following settings on the Alliance module:

    On the Configuration display, set the System field to Controlled by Millennium 32. Follow the description in the instrument's manual for controlling the instrument under Millennium³² to set the GPIB number for the HPLC Module. Make sure that the new GPIB address has not yet been assigned to another instrument and that it is between 2 and 29.

For further settings refer to the general descriptions of commands under Commands and Tips for Third-Party Devices  Waters Alliance 2790/2795 HPLC Modules.

Software Installation

For details about how to add timebases and device drivers to the Server Configuration, refer to Adding, Configuring or Deleting Devices. When you add a driver to the timebase, the configuration dialog or wizard opens automatically. For information about the settings, click the Help button on a page or press F1.
