Operation
Controlling the XY Autosampler through Agilent ChemStation
In the automation table of standard mode, the probe of the XY autosampler
will be moved consecutively from vial 1 of rack 1 to vial 2 and so on. After
having dipped in all the vials of the first rack, the software will move the
probe to vial 1 of rack 2 (3 and 4) and proceed in the same way as before.
In standard mode you can't assign specific vial numbers to different
measurements, for example, blank liquid in vial 1 and 10, control in vial 11
and 12, and samples in vials 2 through 9.
Dissolution Testing Software
The Agilent ChemStation dissolution mode provides you with the possibility
to control the XY autosampler by setting up so-called dissolution run
sequences.
In a dissolution run sequence several measurement actions are supported,
such as:
• measure blank
• measure control
• measure standard
• measure vessels
Due to the fact that Agilent ChemStation follows the logical flow of a
dissolution run, the dissolution run sequence is broken down in three
different consecutive stages:
1 prerun sequence
2 dissolution run
3 postrun sequence
Measurement actions, as specified in the three different run stages, will be
carried out such that the sampler vials and racks will be scanned
consecutively.
Starting with vial 1 of rack 1, which is linked to the first measurement action
defined in the prerun sequence, the sampler will proceed to vial 2 of rack 1
and so on. Depending on the overall number of measurement actions defined,
the sampler will first go through all vials of rack 1, then proceed with rack
two, three and four when appropriate.
