The sample positions are defined as follows:
Each location of the tray definition file is defined by X-, Y-, and Z-coordinates of the
sample rack. The X-coordinates determine the left-right movement of the sampling probe,
the Y-coordinates determine the front-rear movement, and the Z-coordinates determine
the vertical movement.
The origin position is identical with the initialization (home) position of the sampling probe
at the rear of the sample table. The sampling probe returns to this position when the Load
Tray command has been performed.
Figure 21 Principle of sample locations and coordinates
In the various tray definition files, the X- and Y-coordinates for each location in the sample
racks are the distances (in mm) from the origin to the center of the location.
For example, in the PerkinElmer sample racks the rinsing port (location 0) has the
coordinates X = 9 mm and Y = 13 mm.
You can inspect the location coordinates of a tray definition file by means of a text editor
such as Microsoft Notepad (included with MS Windows).
The ability to create customized tray definition files allows the use of customized sample
racks or sample racks supplied from other vendors such as Gilson.
