2.3.4 Connecting a sample changer
For simple automated measurement of several samples and standards
with the pH/Ion Meter the Metrohm Compact Sample Changer 869 can
be connected. Communication takes place via the 6.2148.010 Remote
Box, i.e. the measurements are triggered by the sample changer and
their completion is also transmitted by the pH/Ion Meter via the remote
connection. The individual steps for processing a series of samples or
standards are defined as a method in the sample changer.
Please note that when work is carried out in this way that no sample da-
ta is transferred between the sample changer and the pH/Ion Meter.
This means that the assignment of the report outputs is only possible
by using the consecutive run number (see Section 5.4).
The connection of a Compact Sample Changer 869 and a Dosimat Plus
865 for automatic calibration with standard addition is described here
as an example. A detailed description of how to program a method in
the Compact Sample Changer 869 is given in the corresponding Man-
ual of the instrument.
