Patent number: 10283340Abstract: The present invention is directed to a method and device to generate a chemical signature for a mixture of analytes. The present invention involves using a SPME surface to one or both absorb and adsorb the mixture of analytes. In an embodiment of the invention, the surface is then exposed to different temperature ionizing species chosen with appropriate spatial resolution to desorb a chemical signature for the mixture of analytes.Type: GrantFiled: August 17, 2018Date of Patent: May 7, 2019Assignee: IonSense, Inc.Inventor: Brian D Musselman

Publication number: 20190080894Abstract: 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.Type: ApplicationFiled: November 9, 2018Publication date: March 14, 2019Applicant: IONSENSE INC.Inventors: Jordan Krechmer, Brian D. Musselman

Publication number: 20190066994Abstract: 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.Type: ApplicationFiled: September 28, 2018Publication date: February 28, 2019Applicant: IONSENSE INC.Inventor: BRIAN D. MUSSELMAN
