Patent number: 9534989Abstract: Devices, systems and methods are disclosed which relate to using a wet foam elution method for removal of particles from a flat filter. Particles are captured from the atmosphere onto the flat filter. The flat filter is then placed into an extractor which passes a stream of wet foam through the flat filter. Expansion of the foam works to efficiently remove captured particles. The foam flows from the filter along with the captured particles into a sample container. Once in the sample container, the foam quickly breaks down leaving an analysis ready liquid sample.Type: GrantFiled: November 19, 2013Date of Patent: January 3, 2017Assignee: INNOVAPREP, LLCInventors: Andrew Edward Page, David Scott Alburty, Alec D. Adolphson, Pamela S. Murowchick, Zachary A. Packingham

Publication number: 20160302776Abstract: Devices, systems and methods are disclosed which relate to using wet foam elution for removal of particles from swabs and wipes. This allow users to capture particles from surfaces and recover them by elution into small sample volumes for subsequent detection for human clinical, veterinary, food safety, pharmaceutical, outbreak investigations, forensics, biodefense and bioterrorism response, environmental monitoring, and other applications where collection of samples from surfaces and humans or animals is required. More specifically, the swabs or wipes are used to collect samples in the standard ways that commercially available swabs and wipes are in use today; from, for instance, food preparation surfaces in food plants, from production equipment in pharmaceutical facilities, for collection of dry powders during bioterrorism event response, and for collection of clinical samples such as nasal, throat, nasopharyngeal, and wounds.Type: ApplicationFiled: April 18, 2016Publication date: October 20, 2016Inventors: Alec D. Adolphson, Ann K. Packingham, Andrew E. Page, David S. Alburty, Zachary A. Packingham, John D. Birkenholz, Michael F. Fischer

Publication number: 20140241956Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. A single-use pipette tip includes fluid ports for aspirating the sample and connecting to a concentrating unit.Type: ApplicationFiled: February 26, 2014Publication date: August 28, 2014Applicant: INNOVAPREP LLCInventors: Andrew Edward Page, Zachary A.

Patent number: 8726744Abstract: The present disclosure provides devices, systems and methods for concentrating a fluid sample. A portable or hand-held concentrator is used to draw the fluid sample through a filter into an internal chamber, capturing target particles on the filter. An elution cartridge containing an elution fluid is used to recover the captured particles into a reduced fluid volume. The hand-held concentrator includes a tip, which, when opened, allows the hand-held concentrator to draw the fluid sample into the tip and through the filter wall into the internal chamber. The drawing occurs due to a vacuum or wicking source in the internal chamber of the hand-held concentrator. The target particles are captured on the filter. The elution fluid contains a foaming agent and is held under a head pressure of gas soluble in the elution fluid. The target particles are eluted from the filter into the reduced fluid volume using an elution foam that is formed when the elution fluid is released from the elution cartridge.Type: GrantFiled: February 16, 2011Date of Patent: May 20, 2014Assignee: InnovaPrep LLCInventors: David Scott Alburty, Andrew Edward Page, Alec D.

Patent number: 8677839Abstract: Novel rapid, efficient sample collection systems, devices and methods are disclosed which remove and capture particles, and especially biological particles from surfaces into a liquid sample. The devices were developed primarily for obtaining samples of biological contamination from environmental surfaces. Biological particles, as described here, include bacteria, viruses, and other microorganisms, and other particles of biological origin including nucleic acids, proteins, and toxins.Type: GrantFiled: June 14, 2010Date of Patent: March 25, 2014Assignee: InnovaPrep LLCInventors: Andrew Edward Page, David Scott Alburty, Zachary A. Packingham, Pamela S. Murowchick, Alec D. Adolphson
