Fundamental to the methods with standard ...
Each measuring of a standard (calibrator) can be executed as single, double or triple determination.
Following is shown:
In the white reading window the
averaged
absorbance
of
the
standard is shown.
Below the white reading window
the absorbance 1, 2 and 3 of a
standard are shown.
By [OK] the average of all values is
taken over. Values with 0 are
ignored and excluded from the
calculation. The resulting factor is
calculated from the average of the
standard.
By [CURS.] a value is selected. A
flashing white square marks the
current value.
By [DEL.] a value is deleted and
excluded from the calculation.
By [RESULT] a measuring is
triggered.
The determined resulting factor of a standard measurement is stored together with the corresponding
method number. After renewed selection of this method the last resulting factor is offered as "OLD STD".
The principle of the multiple measurement can also be expanded to all measurements. The correspond-
ing entry can be set invoking a basic method. The parameter is definable in preprogrammed methods
(chapter 7 - METHOD EDITOR).
6.1.5
Fundamental to the methods with multi-standards ...
Linear calibration is used in the case of two calibrators. The absorbance forms a linear diagram with the
concentrations (chapter 8.2.2 - Multi-standard functions).
Nonlinear calibration is used for samples with a nonlinear but reproducible connection between the
absorbance and the concentrations. At least three (maximum 20) calibrators are required for nonlinear
calibration (chapter 8.2.2 - Multi-standard functions).
6.1.6
Fundamental to bichromatic measurements …
The calculation procedures based on endpoint measurement (CP 1 to CP 8, CP 13 and CP 14) can be
executed bichromatic. The zero measurement will be done with a wavelength defined as bichromatic.
The bichromatic wavelength might be not included in the standard set of filters. The bichromatic
wavelength can be set after calling a method (chapter 6 METHOD EDITOR Fig. 6.5).
