No. of cells [ 0...28 ; 2 ]

Number of solutions to be measured if

Technique

Calibration curve [ path + file name ; ]

Selection of the determination file that contains
the desired calibration curves. Accessible if

Sample

is selected for

Calibration

Also accessible with

Calibration

technique “DT

Suppressors with calibration curve” in the CVS and
CPVS mode

Note: To make sure that (for automated opera-
tions with a sample processor) always the latest
calibration file is taken for the calculation; the file
name of the calibration file chosen for parameter

Calibration curve

for the determination of the

sample (with

Calibration

technique "Sample with

calibration curve"), must match with the

Sample

identifier

(see above) defined for recording the

calibration curve (with

Calibration

technique "Re-

cord calibration curve").

No. of replications [ 0...10 ; 2 ]

Number of replications (= total number of measu-
rements) for each variation

(sample, standard ad-

dition, calibration level). For cyclic modes (CV,
CVS, CPVS) the “total number of measurements”
is the

No. of replications

multiplied with the num-

ber of

tal number of measurements” must not exceed
10.

TERS

window contains parameters for preparation procedures and

VA measurement modes. The parameters displayed depend on the
measurement mode selected in the
