Background correction is avoided. Absorbance ratio will be calculated using the

obtained absorbance values.
Absorbance ratio = A(1)/A(2)

Absorption spectrum

The background will be corrected. This is effective when the background level is

even along the wavelength axis. The absorbance at the set correction wavelength

will be subtracted from those at the measuring wavelengths. Calculation is carried

out according to the following equation.
Absorbance ratio = (A(1) - A(correction))(A(2) - A(correction))
