Remark 2 regarding the method.
Calibration [ see below ; Standard addition manual ]
Selection of calibration mode (see also section
5.7):
Standard addition
Standard addition. The number of additions is
defined in the
Determination
tab, the standard
addition solutions are defined in the
Substances
tab, and the Dosimats are defined in the
DOSIMATS
window.
Sample with calibration curve
Sample determination using previously recorded
calibration curves. The determination with the re-
corded calibration curves must be defined in the
Determination
tab.
Record calibration curve
Recording of calibration curves. The number of
additions is defined in the
Determination
tab, the
addition solutions are defined in the
Substances
tab, and the Dosimats are defined in the
DOSIMATS
window.
Addition [ Manual, Automatic ; Manual ]
Selection of manual or automatic standard addi-
tion or recording of calibration curves:
Manual
Manual standard addition or recording of calibra-
tion curves using a pipette.
Automatic
Automatic standard addition or recording of ca-
libration curves using one or several Dosimats.
Technique [ see below ; Batch ]
Selection of measurement technique:
Batch
Measurement without solution exchange.
Batch with solution exchange
Measurement with solution exchange for every
addition or calibration level.
Taken from calibration curve
This option is used automatically if
Sample with
calibration curve
is selected.
Mode
Selection of VA measurement mode (see VA
measurement modes, section 3.2).
Electrode
Selection of electrode (see Electrodes, section
3.1).
