5.1.1. Manual operation
•
Dosing Unit «894/D1 50mL VMS» connected to Dosino
1 has to be prepared with VMS.
•
Suppressor standard solutions and plating bath

•
In the «Run» window on the tab «Determination series»
create a sample table
Fig. 15: Example sample table for suppressor determination
•
To run a calibration with a standard solution select
sample type S TANDARD . For a determination the sample
type S AMPLE has to be selected.
•
No «Sample amount» needs to be defined in the
sample table, since addition volumes for the standard
and the sample are defined in the method commands
