Patent ID: 7570357

Claim:
A visible/near-infrared spectrometry method comprising steps of: irradiating a sample specimen with visible light and/or near-infrared light in the wavelength range 400 nm to 2500 nm or a part of the range; analyzing the spectra of transmitted light, reflected light, and/or transmitted/reflected light obtained from said sample specimen; determining the presence and/or measuring the characteristics of respective specific components present in said sample specimen, wherein said method further comprises steps of: measuring spectra while giving predetermined conditions including at least 3 times repeated irradiations as conditions to generate transitional changes of spectral response pattern while activating water existing within and/or around said sample specimen to promote interaction between water molecules and predetermined component included in said sample specimen; conducting spectral and/or multivariate analysis to detect transitional changes in spectral response patterns; building a model assuming that components of known sample specimen can be determined and/or that characteristics of said components can be measured using the detected transitional changes of the spectral response patterns; conducting the same spectral and/or multivariate analysis on unknown (new) sample specimen while giving the same conditions as said predetermined conditions: and, comparing with the built models to predict components of unknown sample specimen and/or characteristics of the components.
