Claim 15:
16. The computer program product of claim 14, wherein the stored instructions include instructions for performing operations including:
determining the concentration of urea from a detected Raman shift of the excitation light in a frequency range of 900 to 1050 cm−1 based on the modeled excitation of the carbonyl di-amide bond of molecules of urea; and
determining the equivalent concentration of carbon dioxide from a detected Raman shift of the excitation light in a frequency range of 1000 to 1150 cm−1 based on the modeled excitation of the atomic bonds in the carboxyl form of the carbon-containing molecules other than of urea.
