Patent number: 11385210Abstract: A system and method for concurrently measuring odorant concentration and also compensating for changes in relative air density when measuring odor intensity levels may be used to provide more accurate and reliable readings from an odorometer. Odorometers typically measure the concentration of a given target gas in a gas-air mixture.

By measuring the relative temperature and pressure of the air at calibration and when a particular reading is taken, the final reading can be corrected to account for changes in the air density. By correlating the odor intensity readings with odorant concentration readings a wide array of advantages may be realized.Type: GrantFiled: January 26, 2022Date of Patent: July 12, 2022Assignee: HEATH CONSULTANTS, INC.Inventors: Steven Chancey, Paul Wehnert

Patent number: 8845794Abstract: A non-seizing taper used for purged capillary tubing connections in gas chromatography that stops capillary tubing at a predictable position within the taper during installation and maintains space for gas to flow past the capillary tubing. The disclosed taper is an improved component of commonly used purged devices such as inlet liners and purged unions. The arresting aspect of the taper simplifies the process of capillary tubing installation while ensuring that the tubing will reproducibly be positioned in the taper. One or more features of the taper prevent tubing from seizing within the taper so that the devices can be reused and ensure that there is open space for a portion of gas to flow around and past the tubing. The angle of the taper, the dimensions of the taper, and the nature of the features within the taper can be adjusted to meet specific performance, usability and/or manufacturability requirements.Type: GrantFiled: February 3, 2014Date of Patent: September 30, 2014Inventor: Matthew Spangler Klee

Patent number: 8841611Abstract: A gas chromatograph-mass spectrometer (GC-MS) system includes a multi-capillary GC column coupled to a mass analyzer through an ionization interface. The ionization interface includes an ionization device and an ion guide configured for receiving a high-capacity gas-sample flow from the GC column and transmitting a compressed ion beam to the mass analyzer. The ion beam may be converging.Type: GrantFiled: October 15, 2013Date of Patent: September 23, 2014Assignee: Agilent Technologies, Inc.Inventors: Gangqiang Li, Maozi Liu

Publication number: 20140260534Abstract: An improved biocompatible filter for use in liquid chromatography systems such as HPLC or UHPLC The present disclosure addresses the problem of particles bypassing a filter in a liquid chromatography application by design features in the interface between the frit filter and ring that form an improved seal between the ring and frit and prevent leakage around the filter in high measure chromatography. Design features also include frit filters with an internal particle size gradient for pre-column separation activity during filtration.Type: ApplicationFiled: March 17, 2014Publication date: September 18, 2014Applicant: IDEX Health & Science LLCInventors: Mark Hahn, Eric Beemer

Publication number: 20140274660Abstract: A fabric phase sorptive extractor (FPSE) is a sampling device where a flexible fabric is coated with at least one sol-gel derived film that includes at least two of a metal oxide portion, a siloxy portion, and an organic portion, where the gel has at least some amorphous portions. The FPSE is flexible such that it can be used in an extended form or draped over a solid surface to contact a gaseous, liquid, or solid environment and can be manipulated for placement in a container where the absorbed analyte can be removed from the FPSE for instrumental analysis. The FPSE can have specific functionalities that bind to specific analytes or can provide a general sorbent medium for extraction of a wide range of analytes, such that the sampling device can be employed for sampling analytes with biological, environmental, food, pharmaceutical, bio-analytical, clinical, forensic, toxicological, national security, public health, and/or safety implications.Type: ApplicationFiled: March 17, 2014Publication date: September 18, 2014Applicant: THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEESInventors: Abuzar Kabir, Kenneth G.

Patent number: 8808629Abstract: The invention relates to a transfer unit for analysis devices, containing a tube-shaped assembly which can be heated by an electric heater in a programmed manner, a tube (6) which is arranged in the sample chamber (18) and into which the end of a gas chromatographic separating column can be inserted at the end of said tube, and means for introducing carrier gas into the tube (6), said transfer unit being characterized in that a temperature sensor (8) is arranged in the ring chamber (5) between the inner wall of the assembly and the evaporator tube (6). The transfer unit can be a sample introduction device for a gas chromatograph having a sample introduction head (18), and the assembly can be a sample introduction chamber in which an evaporator tube is provided, wherein the end of a gas chromatographic separating column can be inserted into the end facing away from the sample introduction head (18).Type: GrantFiled: September 14, 2009Date of Patent: August 19, 2014Assignee: Joint Analytical Systems GmbHInventor: Joachim Gerstel

Publication number: 20140208825Abstract: This method allows for prediction of subsurface fluid properties (e.g., phase or API gravity) using gas chromatogram data of a small-volume extract. Small volume equates to microliter scale volume (or milligram scale weight) from a subsurface rock sample, where a fluid test may not be available for analysis. The method may also be applied to petroleum liquid samples where drilling fluid or other contaminants preclude accurate direct property measurement. Gas chromatographic data is calibrated to measured petroleum properties; preferably local oils from the same petroleum system, however, a general global calibration can also be used.Type: ApplicationFiled: August 2, 2013Publication date: July 31, 2014Applicant: CONOCOPHILLIPS COMPANYInventors: Albert G.
