How the Type Calculates Sample Concentration
Manually entered
Uses the equation C = K * A, where C is the concentration of the
factor
analyte in the selected units, K is the entered factor, and A is the
absorbance.
Measure single
Divides the sample absorbance value by the average absorbance value
standard
of a single standard. This is in effect a "Standard curve" quantification
(see below) with just one standard.
Standard curve
Uses a simple standard curve based on the absorbance of a set of
standards at a specified wavelength.
Standard curve with
Takes the average of values determined by each of two standard curves
two wavelengths
associated with the specified wavelengths.
Advanced standard
Uses a standard curve generated from a specified equation.
curve
Advanced without
Uses a "single result equation" specified on the
standards
(Calculates the concentration or answer directly from this equation.)
