Feature Description
Analysis wavelength(s) Wavelength(s) to use for the quantitative analysis.
Correction To use uncorrected data, select None.
Single point subtracts the sample absorbance at the entered
wavelength from the absorbance at every data point.
Sloping baseline draws a line between the data points at the
entered wavelengths, finds its Y value at the analytical
wavelength, and subtracts it from the measured absorbance.
Component name Component to quantify.
Unit Component concentration unit. The available units depend on
the Formulas & Units tab settings in Options.
Use user-defined factor Calculates component concentration using the entered factor (K
in the equation C = K *A), with the selected unit.
Use extinction coefficient Calculates component concentration with absorbance (A) equal
to
where ε is the entered extinction coefficient (a constant
dependent on the component and wavelength), c is
concentration in the selected unit, and is 1 cm (the
pathlength).
