2.10.3 System description for Suppressor determination
Electrical connection
Before any instruments are attached to the 797 VA Computrace
Stand, the 797 VA Computrace Stand must be switched off using the
mains switch 14.
A composition with two Dosinos connected to the 797 is recommended for the Sup-
pressor determination with the DT (dilution titration technique) or RC (response curve
technique):
Fig. 25: Electrical connection for Suppressor determination with the 838
Advanced Sample Processor
A 50 mL Dosing Unit filled with "VMS" (with "dilution titration technique") or "Electro-
lyte" (with "response curve technique") is connected to Dosino 1.
A 2 mL Dosing Unit is connected to Dosino 3. With the "dilution titration technique",
it is used to suck in Suppressor standard solution or sample from the sample vessels
on the 838 rack. With the "response curve technique" it is used to dose Suppressor
standard solution from the dosing unit to the measuring cell to record the "response
curve" (see Software Manual section 8.6, or in the Online Help section Suppressor
analysis with 838 Advanced Sample Processor and DT or Suppressor analysis with
838 Advanced Sample Processor and RC).
