Spectrometer Sample Generating And Injecting System Using A Microliter Nebulizer
US Patent:
6859272, Feb 22, 2005
Filed:
Dec 4, 2002
Appl. No.:
10/309316
Inventors:
Michael A. Rutzke - Brooktondale NY, US
Steven D. Sweat - Keene TX, US
Steven D. Sweat - Keene TX, US
Assignee:
Cornell Research Foundation, Inc. - Ithaca NY
International Classification:
G01J003/443
G01N021/73
G01N021/73
US Classification:
356316, 356328, 239423, 239518
Abstract:
A system atomizes liquids into a gaseous medium for formation and injection of a sample into an analytical apparatus, such as a plasma spectrometer. The system employs a high efficiency nebulizer that generates a fine aerosol through use of a nozzle having improved surface wetness characteristics, preferably in combination with a deflecting surface. A desolvator is employed to remove excess solvent from the atomized sample prior to injection into the spectrometer to avoid temperature reduction or extinguishment of the plasma by the sample.
Analytical Nebulizer
US Patent:
2023000, Jan 5, 2023
Filed:
Jul 11, 2022
Appl. No.:
17/811592
Inventors:
- Justin TX, US
Steven D. Sweat - Cedaredge CO, US
Steven D. Sweat - Cedaredge CO, US
Assignee:
Texas Scientific Products LLC - Justin TX
International Classification:
G01N 1/38
B05B 7/04
B05B 1/26
B05B 7/04
B05B 1/26
Abstract:
A thin film induction nebulizer is disclosed herein. The nebulizer has a gas capillary and a liquid capillary that are aligned in the same direction within a nebulizer housing and are substantially aligned with a main axis of the nebulizer housing. The nebulizer includes a liquid opening configured to allow liquid to exit the liquid capillary and a gas orifice configured to allow gas to exit the gas capillary. The liquid capillary opens into a chamber that is formed from a liquid channel having a roughened surface and a cover plate. The cover plate interfaces with the liquid channel to partially seal the chamber. The chamber includes an opening where the liquid opening opens into the chamber and also includes another opening proximal to the gas orifice. The end of the nebulizer housing that is proximal to the liquid opening and the gas orifice includes two angled exterior surfaces.
Analytical Nebulizer
US Patent:
2021028, Sep 16, 2021
Filed:
Jan 19, 2021
Appl. No.:
17/152741
Inventors:
- Argyle TX, US
Steven D. Sweat - Cedaredge CO, US
Steven D. Sweat - Cedaredge CO, US
Assignee:
Texas Scientific Products LLC - Argyle TX
International Classification:
G01N 21/71
H01J 49/10
G01N 21/31
H01J 49/10
G01N 21/31
Abstract:
A nebulizer having a gas capillary and a liquid capillary that are aligned in the same direction within a nebulizer housing is disclosed. The nebulizer includes a nebulizer tip that is substantially parallel to a cross-section of the liquid capillary and to a cross-section of the gas capillary. The tip includes a liquid opening and a gas orifice. The gas capillary may have a non-tapered body and a tapered end. The tip has a roughened surface that allows wetting of the tip with liquid that exits from the liquid opening to form a thin film. The nebulizer may be formed from glass, quartz, one or more polymers, metals, or alloys, or a combination thereof. The nebulizer is capable of handling high solid content samples, and it also offers precision and sensitivity comparable to concentric nebulizers. Methods of introducing a sample into an instrument using the disclosed nebulizer are also disclosed.
