138 Concentration mode
* Calibration curve
There are several possibilities:
– To measure the standard solutions.
– To enter the equation of the calibration curve or the factor value.
– To simulate measurements while entering of the couples of Absorbance/Concentration values
Select an option and press F4 key [Next].
MEASUREMENT OF STANDARD SOLUTIONS
* Standard ID
Enter the identification number of the standards if this one exists.
* Standard manufacturer
Enter the standard manufacturer name if this one exists
* Blank value
YES or NO.
Measure d or not of the reagent blank
Measurement example without reagent blank ( --- ) and with reagent blank ( – ).
It is easy to notice that for a same sample, which absorbance measured against the zero is 0,200 Abs;
the concentration value will not be the same. The blank value is subtracted from the measure.
