column shows the standard addition volume. 0 mL
stands for the sample without added standard.
•
The
second
column shows the reading of the samples with
and without added standard.
•
The
third
column shows the detection rate of the added
standard.

The regression line through the standard addition data points
is displayed.
The correlation coefficient r
2
indicates how close the data
points are to the line.
If the correlation coefficient = 1, the curve is linear.
The concentration shown above the curve is the estimated
concentration of the sample without the added standard.
