Controlling the Sampler 4
Installation, Operation, and Maintenance 85
Part 2, Operation
Setting Parameters on a 5890 Series II GC
The injection of a sample into a 5890 Series II GC is controlled by the G2912A
Controller. The controller stores the order of vials handled, vial location, wash
method, injection volume, injector plunger speed, dwell time, sampling depth,
and inlet and tray configuration for one or two injectors. During operation, the
GC first indicates a ready condition to the sampler; the sampler then uses
these stored parameters to perform an injection. The controller starts the GC
run if the injection was successful.
Users can access and change these stored parameters using the G2911-64000
(G2911AA) Agilent Automated Liquid Sampler Controller for 5890 GC
application. This is a standalone application and information stored in the
sampler controller is not accessible by Agilent data acquisition systems
applications like the Agilent ChemStation or Cerity NDIS. If your lab sampling
procedure does not require constant changing of these settings, this controller
application need only run when necessary. Labs requiring the flexibility of
changing these parameters between the processing of groups of samples
should keep this program open in Microsoft Windows alongside their data
acquisition software.
For a GC with front and back injectors, leaving an injector door open before
the first sample vial in a sequence is processed disables that injector for the
duration of the samples processed. This is a convenient method for
temporarily disabling one injector that is not required without making a
configuration change using the Agilent Automated Liquid Sampler Controller
for 5890 GC application. Opening an injector door at a later time when
processing samples temporarily pauses the injection sequence, and the GC
cannot continue until the door is closed.
The G2911-64000 (G2911AA) Agilent Automated Liquid Sampler Controller
for 5890 GC application’s main window is shown in Figure 37.
NOTE
When using the G2913A injector with 1-sample turret, the solvent capacity of each injector
is six solvent bottles and the waste capacity is four bottles. When using the G2613A
injector the solvent capacity of each injector is two solvent bottles. The waste capacity
when using the G2613A injector is two bottles when using the tray and one bottle (waste
A) when not using the tray. The B2 solvent bottle on the 3-sample turret is not available
when using the G2613A injector with the 5890GC.
