4.2.7 Linear Regression Mode
Linear Regression:
Description:
The instrument accepts a number of
calibrators (from 2 to 7), subsequently
calculating concentrations based on the
best fit (linear regression).
Data may be entered for linear-linear, ln (=
natural log)-linear, linear-ln, or ln-ln
calculations.
A logit-log calculation is also available.
Blanking, graphing and editing options are
available.
Absorbance, or ln of (1000 * absorbance),
is always on the “Y” axis, and
concentration, or ln of concentration, is
always on the “X” axis.
