Device Type:

GC Autosampler

Device Driver:

Fisons: FisonsAS800_Sampler or
ThermoFinnigan/Thermoquest/TSP: AS2000 GC Sampler (for operating the autosampler in dual operation)

Supported Hardware Options:

No special options available.

License:

Timebase Class 1

Connection:

RS-232 cable (For cable details, refer to  ThermoQuest//Fisons Cable.)

Hardware
Prerequisites:

• An A/D converter is required for data acquisition. A UCI Universal Chromatography Interface including the appropriate signal cables may be used.

• A free RS-232 port is required for control.

Software
Prerequisites:

No software prerequisites known.

Control Panel:

FISAS800.pan

Device Connection:

A special cable (Thermo Scientific part no. 8914.0148) is required to connect the autosampler to the PC (refer to  ThermoQuest/Fisons Cable).

Use a 37-pin connecting cable to connect the Fisons GC Autosamplers to the Fisons 8000 Gas Chromatograph. When the injection is completed, the GC autosampler sends the signal to the GC, which in turn sends it to Chromeleon via a relay. The pins 12 and 24 of the GC AUX connector are used. Connect the signal and GND lines of a remote input to these.

AUX Connector  (for example, UCI-100)

(25-pin; Sub-D, female)  (9-pin, Sub-D, male)

12 ----------- Signal

24 ----------- GND (0V)

In the Server Configuration, specify the remote input that is used by the Fisons AS800 autosampler under Inject Port on the Sampler tab page!

Device Settings:

The following communications parameters must be used: 9600 Baud, 8 Data Bits, No Parity, 1 Stop Bit, Rts/Cts handshake.

Some Fisons AS800 GC samplers are set to a baud rate (by the manufacturer) that is not suitable for the Chromeleon device Device Drivers.

When turning on the autosampler, simultaneously press the Meth and Seq keys to check the baud rate setting. The following information will be displayed:

AS800 SET UP: b9600

ACT INJ SMP SYR MAN

The value on the top right is the baud rate setting. This information may not be available in previous firmware versions. If this is the case, press the EXIT key to leave the Setup menu.

If the baud rate is not set to 9600, move the cursor to the baud rate field using the left arrow key (<). Set the new baud rate, using the up and down arrow keys. Press the Exit key to leave the Setup menu.

Device Settings
(Dual Operation):

Only if you want to operate two autosamplers in dual operation mode:

On the autosampler display, set Sync to Twin (program page PP14).
