Apparatus And Method For Noninvasive Chemical Analysis, Robert A. Lodder Sep 1996

Apparatus And Method For Noninvasive Chemical Analysis, Robert A. Lodder

Pharmaceutical Sciences Faculty Patents

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 …


Apparatus And Method For Multiple Wavelength Of Tissue, Robert A. Lodder, Lisa A. Cassis Aug 1995

Apparatus And Method For Multiple Wavelength Of Tissue, Robert A. Lodder, Lisa A. Cassis

Pharmaceutical Sciences Faculty Patents

An apparatus for analyzing the chemical composition of tissue includes a near infrared light source, a fiber-optic probe, a mechanism for directing the light from the light source onto the tissue and detectors for detecting light reflected by the tissue. The light source transmits an incident beam having a wavelength ranging from 1000 to 2500 nm. A compound parabolic concentrator (CPC) is connected to a distal end of the fiber optic probe to focus or concentrate the wavelengths of light simultaneously and in parallel on a particular spot of tissue. Alternatively, an inverted, substantially conical reflector is positioned to scatter …

Method And Apparatus For Detecting Microorganisms Within A Liquid Product In A Sealed Vial, Robert A. Lodder Nov 1992

Method And Apparatus For Detecting Microorganisms Within A Liquid Product In A Sealed Vial, Robert A. Lodder

Pharmaceutical Sciences Faculty Patents

An apparatus and method are provided for the noninvasive and nondestructive detection of microorganisms within a liquid product contained within a sealed vial. The apparatus includes a near-IR light source that produces both incident and reference beams having a wavelength between 800 and 2500 nm and, more preferably, 1100 and 1360 nm. The apparatus also includes an integrating sphere having incident and reference beam ports and a sample window opposite the incident beam port. A detector is mounted in the integrating sphere substantially adjacent the sample window. A substantially U-shaped mirror is provided to hold the vial. The U-shaped mirror …
