Patent number: 11075068Abstract: A method and apparatus that ionize vapors for their chemical analysis is described. The new ionizer improves the ionization efficiency by reducing dilution of sample molecules and improving transmission of ions to the analyzer. This is accomplished by a new flow configuration, in which a stream of clean gas focuses the ions towards the analyzer. A deflector prevents the formation of turbulent perturbation, and the ionization maintains a laminar regime without the need for additional separating walls or electrodes. The flow within the ionizer is configured so that contaminants released by the inner walls of the ionizer do not reach the ionization region. The resulting ionizer improves the ionization efficiency, and the background levels for low volatility species. This makes it ideal for the analysis of low volatility species in the gas phase. One application of this ionizer is the analysis of human breath in real time.Type: GrantFiled: November 20, 2017Date of Patent: July 27, 2021Assignee: FOSSIL ION TECHNOLOGYInventor: Guillermo Vidal-de-Miguel

Patent number: 10543334Abstract: A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.Type: GrantFiled: March 16, 2017Date of Patent: January 28, 2020Assignee: Mallinckrodt Hospital Products IP LimitedInventor: Scott I.
