  • Evaluating a vessel for suitability for containing fluid
    Patent number: 9664212
    Abstract: A method for evaluating a vessel for suitability to contain a fluid includes providing a vessel and forming a polished surface portion of the vessel by removing oxidation and/or contaminants from a portion of the vessel. The method further includes applying a focused laser to the polished surface portion to form plasma on the polished surface portion, and determining whether the vessel is suitable for containing a fluid based on silicon content of the polished surface portion. The silicon content is estimated based on light emitted from the plasma.
    Type: Grant

  • Vaporization device and method for imaging mass spectrometry
    Patent number: 8598521
    Abstract: Methods and apparatus for analyzing samples are disclosed. The samples are analyzed by vaporizing molecules from a sample in a sample area with a femtosecond laser beam under ambient conditions, ionizing the vaporized molecules with electrospray ionization under the ambient conditions to form ions; and analyzing and detecting the ions.
