Installing and Controlling Third-Party Devices
Gilson 151/152 and 156 UV/VIS Detectors: Installation

Device Type:

Single-channel UV detector: Gilson 151/152

Two-channel UV detector: Gilson 156

Device Driver:

Gilson: 152 UV/VIS Detector

Gilson: 156 UV/VIS Detector

 

What is required?

License:

Timebase Class 3

Connection:

Required components:

  • Modem cable. (For more information, refer to  Modem Cable (1:1 Cable) in the Appendix of the Hardware Installation section. The Thermo Scientific part number for the cable is 8914.0144A.)

  • An A/D converter is required for data acquisition. For example, a UCI Universal Chromatography Interface, with the appropriate signal cables may be used.

Hardware
Prerequisites:

A free RS-232 port (Contrary to most other Gilson instruments, it is also possible to connect the detector via the UCI or a COM port.)

Control Panel:

Gilson_156_Det.pan

Hardware Installation

Device Connection:

Use a modem cable to connect the detector. (For cable details, refer to  Modem Cable (1:1 Cable) in the Appendix of the Hardware Installation section.)

Device Settings:

Data transfer is performed at 19200 baud. Please check the baud rate setting on the detector. If necessary, change the setting to 19200 baud. (For more information, refer to the instrument's manual.)

In addition, set the GSIOC address. The default setting is 16. (Refer to the instrument's manual for the details.) Make sure that the value entered on the instrument corresponds to the value in the Server Configuration program (set during installation of the Gilson UV/VIS detector).

Restrictions:

Chromeleon cannot check whether the lamp is burning. Therefore, verify that the lamp is burning before you start data acquisition.

 

Software Installation

Install the Device Driver in the Chromeleon Server Configuration. (For more information about the program, refer to Software Installation and Communication  The Server Configuration Program.)

  1. Start the Chromeleon server.

  2. Start the Server Configuration program.

  3. Add the detector to the timebase. Select Add Device on the Edit or context menu, and then select Gilson from the Manufacturers list box and 152 UV/VIS Detector or 156 UV/VIS Detector from the Devices list box.

  4. The following settings are required:

On the General tab page, select a free COM port on the interface card and enter the GSIOC address set on the instrument. (This address is displayed on the instrument's rear panel.

Open the Signal Configuration dialog box by double-clicking the channel(s) on the Signals tab page. Assign a channel to the signal and name the signal in the Signal Name field according to the selected detector type.

The Error Levels tab page classifies the severity of any errors that occur. It is generally not necessary to change the default settings.

  1. To control the Gilson UV detectors, connect the Gilson_156_Det_118.pan control panel in the Chromeleon client to the corresponding timebase (if necessary, remove those components that are not required from the control panel).

Application

 Tip:

With the Gilson 151/152 and 156 UV/VIS detectors, be sure that the lamp is burning and sufficiently warm before you start data acquisition (warming up the lamp also reduces the baseline drift to a minimum). You can start data acquisition even when the lamp is turned off. You will not even receive an error message, as the instrument does not output the lamp status (On or Off).

 Note:

For consistency reasons, the Peak Width and Sensitivity parameters (on the instrument) of UV detectors are called Response and Range in Chromeleon.

Further Information

 Tip:

For more installation details, refer to the manual for the instrument.
