Filed:

Mar 11, 2013

Appl. No.:

13/794144

Inventors:

Nathan Porter - Kaysville UT, US
Anthony D. Rands - Orem UT, US

Assignee:

TORION TECHNOLOGIES, INC. - AMERICAN FORK UT

International Classification:

G01N 1/24

US Classification:

73 2337, 7386464

Abstract:

A system and method for improving operation of a needle trap by changing a flow path through a needle trap to enable a needle to draw a fluid sample into a working end of the needle and out through the side hole, wherein drawing the sample through the side hole eliminates the possibility of a leak through the side hole while drawing a fluid sample into the working end.

Assignee:

Dionex Corporation - Sunnyvale CA

International Classification:

B01L 1100
B01D 1100

US Classification:

422101

Abstract:

An apparatus for receiving chemical compounds carried in a high pressure effluent fluid stream from supercritical fluid extraction. The apparatus includes a heated conduit connected to supercritical fluid extraction device through which an effluent stream flows. The exit port of the heated conduit is located within the airspace of a decompression zone which is free of liquid. A liquid solvent chamber is provided in open communication with the downstream end of the decompression zone into which the effluent stream flows for the recovery of chemical compounds therein.

Appl. No.:

17/617467

Inventors:

- Waltham MA, US
Nathan Porter - Kaysville UT, US
Edgar D. Lee - Wallsburg UT, US

International Classification:

G01N 1/40

Abstract:

The present invention is a system and method for improving extraction of analytes from a solution by disposing a plurality of polydimethylsiloxane(PDMS) particles in a thin layer on an inner wall of an extraction vial, by increasing a surface area and volume of particles disposed to extract analytes from the solution and thereby increasing extraction capacity and speed for gas chromatography-mass spectrometry (GC-MS) analysis.

US Patent:

20200103377, Apr 2, 2020

Filed:

Aug 9, 2019

Appl. No.:

16/537019

Inventors:

- Waltham MA, US
Nathan L. Porter - Kaysville UT, US
Randall W. Waite - Springville UT, US

International Classification:

G01N 30/30

Abstract:

Certain configurations described herein are directed to gas chromatography devices. In some instances, the gas chromatography devices may comprise at least one heating device which can be moved along a chromatography column to provide a thermal gradient to the chromatography column. In other instances, the gas chromatography devices may comprise a heating device that can receive a moving chromatography column to provide a thermal gradient to the chromatography column. The gas chromatography devices may be configured as portable devices which can be used to perform remote analyses.

Nathan L. Porter - Kaysville UT, US
Anthony D. Rands - Orem UT, US
Randall W. Waite - Springville UT, US

International Classification:

G01N 30/30

Abstract:

A system and method for performing field-portable GC/MS measurements for the rapid sampling and measurement of high temperature boiling semi-volatile organic compounds in environmental samples, wherein other column bundles have cold spots that may prevent high temperature boiling semi-volatile components from eluting the GC column, this new design may eliminate those cold spots on the GC column.
