Preferred Label : difference absorption spectroscopy;
IUPAC definition : A highly concentrated analyte in an analytical sample can be determined with better
precision by replacing the blank (reference) cell by one containing a solution of
the analyte or other absorber of known concentration; this is known as difference
absorption spectroscopy. Difference spectra can also be obtained by computer or other
subtraction methods.;
