  • Process to measure PPB levels of dissolved copper in jet fuels and other non-aqueous fluids using a colorimetric process
    Patent number: 7378281
    Abstract: A method of measuring the concentration of metal ions in a sample comprising the steps of: providing a sample comprising a nonpolar, liquid hydrocarbon, suspected of containing a metal ion; adding a dye such as a spirobenzopyran dye or bathocuproine and a reducing agent to the sample; wherein the dye forms a complex with the metal ion; wherein the complex has a spectral shift in light absorbance relative to the dye; observing the spectral shift; and calculating the concentration of the metal ion in the sample.

  • Apparatus for performing surgery inside the human retina using fluidic internal limiting membrane (ILM) separation (films)
    Patent number: 6210357
    Abstract: A method and apparatus for performing surgery inside the human retina using fluidic internal limiting membrane separation (FILMS) to remove the internal limiting retinal layer from the neural retinal layer at the macula. The method comprises inserting a hollow microcannula between the retinal internal limiting membrane and the neural retinal layer at or near the macula and injecting a sterile fluid, such as sodium hyaluronate, through said microcannula and thereby raising the macular internal limiting membrane retinal layer away from the neural retina such that it can then be removed by conventional means, while simultaneously smoothing the neural retina by localized pressure tamponad. The apparatus comprises a hollow microcannula having a proximal end a distal end and a distal tip. The distal end is shaped to conform tangentially to the surface of the retina.
