Abstract
A method and apparatus are provided for magnetohydrodynamic acoustic-resonance, near-IR spectroscopy. The method includes a step of applying to a subject under study a magnetic field having a strength between 2,00-10,000 gauss, near-IR radiation having a wavelength between 800-3,000 nm and an acoustic wave having a frequency between 10 khz -1 Mhz. The method also includes the steps of inducing vibration of ions in the magnetic field and detecting an electric wave generated magnetohydrodynamically by the acoustic wave induced vibration of the ions. Next is the collecting of the electrical, acoustical and near-IR spectra and the analyzing of the collected spectra. The spectra is analyzed in a hyphenated, multidimensional fashion.
