Calculation Method
Point to point
Linear regression
Select the calculation method to be used for the calibration curve.
The point to point curve fit draws a straight line between adjacent
data points and considers each line segment to be a separate
calibration line governed by its own equation.
A linear regression statistically determines the line that best fits the
pattern of all data points.
Zero Shift
Select this item to shift the calibration curve through origin.
Multiple Injections
If this item is selected, multiple injections are made from a single
aliquot of standard solution. This larger standard aliquot is drawn in
the syringe in one aspiration an is sufficient to accommodate all of
the repeat injections
File Name
