Patent ID: 8629399

Claim:
A method of measuring biological processes, the method comprising: directing a mid-infrared signal into an initial sample of a biological process before a biologically active phase; detecting a sample spectrum from the mid-infrared signal to form an initial sample spectrum before the biologically active phase; generating an initial reference spectrum through a reference media comprising water, fermentation material, fiber optic cable, or combinations thereof, before the biologically active phase; combining the initial sample spectrum and the initial reference spectrum to form an adjusted initial sample spectrum; subtracting the adjusted initial sample spectrum from the adjusted sample spectrum to form a difference spectrum; directing a the mid-infrared signal into a sample of a the biological process during the biologically active phase; detecting a sample spectrum from the mid-infrared signal to form a sample spectrum; generating a reference spectrum through a the reference media; and combining the sample spectrum and the reference spectrum to form an adjusted sample spectrum.
