2. Press
Measure Blank
.
If the Single Cell Changer is installed, remove the blank and place the standard in the cell
changer.
3. Press
Units/Standard
to set the units and measure the standard.
4. Press
Enter Conc
, enter the concentration value of the standard and press
Enter
.
5. Press
Select Units
, highlight the appropriate unit in the list and press
Enter
.
6. Press
Measure Standard
.
The instrument measures the absorbance of the standard and displays the absorbance and
calculated factor.
Using Conc/Factor to Measure Concentration
In this mode a concentration factor is used to determine the concentration of samples. The
concentration of unknown samples is determined ratiometrically from the entered factor. The
measurement can be expressed mathematically as
(Abs / %T of Sample) * Factor = Concentration of Sample
where the factor is entered, the Abs/%T of the sample is measured, and the sample
concentration is calculated.
To use Conc/Factor to measure concentration
1. If necessary, press
Change Mode
to switch to the Conc With Factor mode.
2. Press
Units/Factor
to set the factor and select the units.
3. Press
Enter Factor
.
4. Type the desired factor value.
