Detection Of Gas Leakage

View page
US Patent:
8201438, Jun 19, 2012
Filed:
Apr 16, 2009
Appl. No.:
12/424791
Inventors:
Steven Thornberg - Peralta NM, US
Jason Brown - Albuquerque NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
G01M 3/34
US Classification:
73 493, 73 492
Abstract:
A method of detecting leaks and measuring volumes as well as an apparatus, the Power-free Pump Module (PPM), that is a self-contained leak test and volume measurement apparatus that requires no external sources of electrical power during leak testing or volume measurement, where the invention is a portable, pneumatically-controlled instrument capable of generating a vacuum, calibrating volumes, and performing quantitative leak tests on a closed test system or device, all without the use of alternating current (AC) power. Capabilities include the ability is to provide a modest vacuum (less than 10 Torr), perform a pressure rise leak test, measure the gas's absolute pressure, and perform volume measurements. All operations are performed through a simple rotary control valve which controls pneumatically-operated manifold valves.

US Patent:
8230722, Jul 31, 2012
Filed:
Mar 16, 2010
Appl. No.:
12/724476
Inventors:
Steven M. Thornberg - Peralta NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
G01M 3/34
US Classification:
73 493
Abstract:
A system is provided for testing the hermeticity of a package, such as a microelectromechanical systems package containing a sealed gas volume, with a sampling device that has the capability to isolate the package and breach the gas seal connected to a pulse valve that can controllably transmit small volumes down to 2 nanoliters to a gas chamber for analysis using gas chromatography/mass spectroscopy diagnostics.

Real-Time Monitoring Of Volatile Organic Compounds Using Chemical Ionization Mass Spectrometry

View page
US Patent:
59627743, Oct 5, 1999
Filed:
Apr 17, 1998
Appl. No.:
9/062469
Inventors:
Curtis Dale Mowry - Albuquerque NM
Steven Michael Thornberg - Peralta NM
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
F16K 3102
B01D 1508
G01N 3002
US Classification:
73 2337
Abstract:
A system for on-line quantitative monitoring of volatile organic compounds (VOCs) includes pressure reduction means for carrying a gaseous sample from a first location to a measuring input location maintained at a low pressure, the system utilizing active feedback to keep both the vapor flow and pressure to a chemical ionization mode mass spectrometer constant. A multiple input manifold for VOC and gas distribution permits a combination of calibration gases or samples to be applied to the spectrometer.
