  • Patent number: 9390899
    Abstract: In various embodiments of the invention, a cargo container can be monitored at appropriate time intervals to determine that no controlled substances have been shipped with the cargo in the container. The monitoring utilizes reactive species produced from an atmospheric analyzer to ionize analyte molecules present in the container which are then analyzed by an appropriate spectroscopy system. In an embodiment of the invention, a sorbent surface can be used to absorb, adsorb or condense analyte molecules within the container whereafter the sorbent surface can be interrogated with the reactive species to generate analyte species characteristic of the contents of the container.

  • Publication number: 20160042931
    Abstract: The present invention is directed to a method and device to desorb an analyte using heat to allow desorption of the analyte molecules, where the desorbed analyte molecules are ionized with ambient temperature ionizing species. In various embodiments of the invention a current is passed through a mesh upon which the analyte molecules are present. The current heats the mesh and results in desorption of the analyte molecules which then interact with gas phase metastable neutral molecules or atoms to form analyte ions characteristic of the analyte molecules.

  • Patent number: 8558170
    Abstract: In various embodiments of the invention, a device permits more efficient collection and transmission of ions produced by the action of a carrier gas containing metastable neutral excited-state species into a mass spectrometer. In one embodiment of the invention, the device incorporates the source for ionization in combination with a jet separator to efficiently remove excess carrier gas while permitting ions to be more efficiently transferred into the vacuum chamber of the mass spectrometer. In an embodiment of the invention, improved collection of ions produced by the carrier gas containing metastable neutral excited-state species at greater distances from between the position of the analyte and the position of the mass spectrometer are enabled.
