Publication number: 20190226968Abstract: An apparatus and method for condensationally enlarging particles in a flow of air or other gas. The apparatus includes a coiled tube having a tube diameter and a coil diameter, the tube having an input receiving the flow and an output, the tube having a length between the input and the output. The walls of the tube are wetted with a condensing fluid. The walls of the first portion of the coiled tube are held a temperature that is lower than the highest temperature in the second portion of the tube. The tube may have a third vapor recovery portion with wall temperature lower than the highest temperature in the second portion, and which optionally may not be coiled. While heating and cooling, the method includes introducing a flow into an interior of the tube at an input, the flow moving the output.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Applicant: AEROSOL DYNAMICS INC.Inventors: Susanne Vera Hering, Steven Russel Spielman, Gregory Stephen Lewis

Patent number: 10252237Abstract: An apparatus and method for creating enlarged particles in a flow. The apparatus includes a coiled tube having a tube diameter and a coil diameter, the tube having an input receiving the flow and an output, the tube having a length between the input and the output. A heater heats a first portion of the tube along a first, longitudinal portion of the tube, and a cooler cools a second, longitudinal portion of the tube along at least a second portion of the tube. The method includes heating a first portion of the tube along a first longitudinal portion of the tube, and simultaneously cooling a second portion of the tube along at least a second longitudinal portion of the tube. While heating and cooling, the method includes introducing a flow into an interior of the tube at an input, the flow moving the output.Type: GrantFiled: October 19, 2015Date of Patent: April 9, 2019Assignee: Aerosol Dynamics Inc.Inventors: Susanne Vera Hering, Steven Russel Spielman, Gregory Stephen Lewis

Patent number: 9610531Abstract: A system and method for particle enlargement with continuously wetted wicks includes a container into which a flow of particle-laden air is introduced in a laminar manner through an inlet and to an outlet. The container has a first section, a second section and a third section though which the particle-laden air flows between the inlet and the outlet. The temperature of the second section is warmer than that of the first section at the inlet and the third section at the outlet. In one embodiment, a continuous wick spanning an interior wall of the first second, second section and third section, said wick being capable of internally transporting liquid water along its length is provided.Type: GrantFiled: October 1, 2013Date of Patent: April 4, 2017Assignee: AEROSOL DYNAMICS INC.Inventors: Susanne Vera Hering, Steven Russel Spielman, Gregory Stephen Lewis, Nathan Michael Kreisberg

Patent number: 9579662Abstract: A particle charging method and apparatus are provided. An ion source is applied to a particle laden flow. The flow is introduced into a container in a laminar manner. The container has at least a first section, a second section and a third section. The first section includes wetted walls at a first temperature. A second section adjacent to the first section has wetted walls at a second temperature T2 greater than the first temperature T1. A third section adjacent to the second section has dry walls provided at a temperature T3 equal to or greater than T2. Additional water removal and temperature conditioning sections may be provided.Type: GrantFiled: October 1, 2013Date of Patent: February 28, 2017Assignee: AEROSOL DYNAMICS INC.Inventors: Susanne Vera Hering, Steven Russel Spielman, Gregory Stephen Lewis

Patent number: 9395281Abstract: A parallel plate dimensional electrical mobility separator and laminar flow water condensation provide rapid, mobility-based particle sizing at concentrations typical of the remote atmosphere. Particles are separated spatially within the electrical mobility separator, enlarged through water condensation, and imaged onto a CCD array. The mobility separation distributes particles in accordance with their size. The condensation enlarges size-separated particles by water condensation while they are still within the gap of the mobility drift tube. Once enlarged the particles are illuminated by a laser. At a pre-selected frequency, typically 10 Hz, the position of all of the individual particles illuminated by the laser are captured by CCD camera. This instantly records the particle number concentration at each position. Because the position is directly related to the particle size (or mobility), the particle size spectra is derived from the images recorded by the CCD.Type: GrantFiled: October 8, 2013Date of Patent: July 19, 2016Assignee: BROOKHAVEN SCIENCE ASSOCIATES, LLCInventors: Jian Wang, Susanne Vera Hering, Steven Russel Spielman, Chongai Kuang

Patent number: 9028775Abstract: This technology is a method and apparatus for the semi-continuous measurement of the concentration of constituents of airborne particles which couples a laminar flow, water condensation particle collector to a microfluidic device for assay of particle chemical composition by electrophoresis. The technology has been used for the assay of sulfates, nitrates, chlorides, and organic acids contained in fine and submicrometer atmospheric particles. For these compounds the apparatus and method described is capable of one-minute time resolution at concentrations at the level of micrograms of analyte species per cubic meter of air. Extension to other analytes is possible.Type: GrantFiled: September 27, 2011Date of Patent: May 12, 2015Assignees: Aerosol Dynamics Inc., Colorado State University ResearchInventors: Susanne Vera Hering, Gregory Stephen Lewis, Steven Russel Spielman, Charles Sherman Henry, Scott Douglas Noblitt, Jeffrey Lee Collett, Jr.

Publication number: 20150024379Abstract: An aerosol collection system and method. The system includes a bio-aerosol delivery device configured to supply bioparticles in a gas stream, a moisture exchange device including a partition member coupled to the gas stream and configured to humidify or dehumidify the bioparticles in the gas stream, and an aerosol collection medium downstream from the moisture exchange device and configured to collect the bioparticles. The method includes delivering bioparticles in a gas stream, humidifying or dehumidifying the bioparticles in the gas stream by transport of water across a partition member and into a vapor phase of the gas stream, and collecting the bioparticles by a collection medium.Type: ApplicationFiled: February 19, 2013Publication date: January 22, 2015Applicants: RESEARCH TRIANGLE INSTITUTE, AEROSOL DYNAMICS INC.Inventors: David S.
