Working with the TO 7280 / TW 7650 and TitriSoft
3.3
Optionally, the TO 7280 can also be operated via the PC software TitriSoft. For general information on working
with the PC software, see the operating instructions for the corresponding TitriSoft version. Working with the oven
and the changer is possible from TitriSoft 3.5.0. The following examples are based on TitriSoft 3.5.0 and may
differ from the actual display.
The Examples database included in the scope of delivery contains example methods for working with a
headspace oven and changer and can be used directly. Adaptations to the specific sample, e.g. temperature,
may be necessary.
If the TO 7280 / TW 7650 is to be controlled via TitriSoft, no method with activated oven must be
selected on the titrator, otherwise the communication between TitriSoft and oven is blocked!
The method
«
with Headspace TitriSoft
» is available as default method.
3.3.1
The titration command «Coulometer»
Methods are created in the analysis center and the analysis procedures are programmed. A titration module is
available for working with the TO 7280 / TW 7650, which automatically regulates the titration procedure (Fig. 67).

The «
Coulometer
» command is selected and built into the method (Fig. 68).

In the
“
Type
” and “
Result
” area, the variable is defined and named on which the absolute result of the titration in
µg water is stored. As a rule, the variable
“
Type
” is “Result” and the “
Result
” name is “Water [µg]” (Fig. 69).
