Note: 1 DEGREE THRU.0 calculates the best straight line fi t through the data
points and intersects with the origin at 0 ppm, 0 absorbance. This is a classical
Beers Law calibration. If a one point calibration has been performed, the 1
DEGREE THRU.0 curve fi t must be chosen. 1 DEGREE calculates the best
straight line fi t but without forcing the line through the origin. The minimum
number of standards needed for a calibration is one for 1 DEGREE THRU.0 and
two for 1 DEGREE.
NOTE: 2 DEGREE and 3 DEGREE calculations are not available yet.
