  • Sample introduction interface for analytical processing
    Patent number: 6867415
    Abstract: An interface for introducing a non-gaseous sample as a predetermined gaseous form into an accelerator mass spectrometer which comprises a nebulizer that receives the non-gaseous sample to provide a fine spray of the sample, a converter that receives at least a portion of said fine spray and converts the desired elements to the predetermined gaseous form and a flow line that transports the predetermined gaseous form to the accelerator mass spectrometer.
    Type: Grant
    Filed: August 23, 2001
    Date of Patent: March 15, 2005
    Assignees: Newton Scientific, Inc., Massachusetts Institute of Technology
    Inventors: Barbara J. Hughey, Paul L. Skipper, John S. Wishnok, Ruth E. Shefer, Naomi A. Fried, John T. Mehl, Steven R. Tannenbaum
  • Sample introduction interface for analytical processing of a sample placed on a substrate
    Patent number: 6707035
    Abstract: An interface system for introducing a non-gaseous sample as a predetermined gaseous form into an analytical instrument which comprises a substrate that receives the non-gaseous sample and a directed energy source that heats at least a portion of said substrate containing the non-gaseous sample to convert the sample to the predetermined gaseous form.
