  • Patent number: 9010174
    Abstract: A method and a device for the analysis of gas components of a matrix employ two sensors, which each comprise a cavity enclosed by a membrane. Both membranes, each on one side of the matrix and on the other side, are exposed to a purge gas and subsequently, the timeline of the differential pressure ?ps starting at a start time tA is measured, which is created between the sensors as a consequence of permeation of gas components of the matrix and/or the purge gas through both membranes. From the timeline, a point of time tE is determined, at which the measured differential pressure equals the differential pressure at the point of time tA, whereby the gas component of the matrix, which is different from the purge gas, and its genesis is determined from the time difference ?t=tE?tA.

  • Publication number: 20150059444
    Abstract: A gas concentration image (i.e., concentration vs. position data) in a cross section through a gas plume is obtained. Such measurements can be obtained by using a 2D array of gas sample inlets, or by moving a 1D array of gas sample inlets through the gas plume. By combining a gas concentration image with ambient flow information through the surface of the gas concentration image, the leak rate (i.e., gas flux) from the leak source can be estimated. Gas samples are simultaneously acquired by filling two or more gas sample storage chambers. This is the default operation mode, which is convenient to regard as recording mode. The other operating mode is a playback mode, where the gas samples in the gas sample storage chamber are sequentially provided to a gas analysis instrument. Gas collection via line pixels can be used to compensate for vertical wind speed variation.

  • Patent number: 8875559
    Abstract: A system and method for taking a sample of hydrogen gas and conditioning that sample so that extremely low levels of contamination can be more accurately detected. Initially a sample of hydrogen gas is captured and isolated in a collection chamber. A hydrogen permeable membrane is provided having a first side and a second side. The first side of the hydrogen permeable membrane is exposed to the gas sample held within the collection chamber. The hydrogen gas contained within the gas sample begins to permeate through the hydrogen permeable membrane and exit the collection chamber. This causes the pressure of the gas sample within the collection chamber to decrease. Since contaminants remain in the collection chamber, the concentration of contaminants within the remaining sample increases exponentially. The residual pressure within the collection chamber is measured and converted into a contaminant level reading.

  • Patent number: 8726720
    Abstract: A particulate monitoring system includes a conduit in which to a pass a fluid sample from an input port to an output port. The particulate monitoring system receives a fluid sample inputted to the conduit through the input port. The fluid sample can include different sizes of particulate matter. The particulate monitoring system controls a flow of the fluid sample through the conduit to age the particulate matter. Gravitational forces cause a portion of the particulate matter in the fluid sample to fall into a basin as opposed to being exhausted through the output port, which is disposed at a vertically higher level of the conduit than the input port. Thus, the particulate monitoring system outputs a portion of the original particulate matter in the fluid sample (e.g., particulate matter that does not drop into the basin out due to gravity) for analysis.

  • Patent number: 8459098
    Abstract: The present invention discloses a physiologic sampling pump (PSP) which uses at least one valve placed near the sampling medium to modulate air sampling to follow a person's inhalation rate and to obviate the sluggishness inherent in prior art PSPs caused by varying pump speed and by the propagation time through an air tube that connects the collection medium to prior art pumps thereby also obviating limitations inherent in system response, functionality, and accuracy. Moreover, by maintaining an essentially constant air flow through a cyclone at all times and through the collection medium while sampling, the present invention operates at known collection efficiencies, and is therefore capable of size-selective sampling of particulates as opposed to prior art PSPs that by varying the magnitude of air flow, make the separation efficiencies of pre-collection devices indeterminate and the samples worthless.

  • Patent number: 8266945
    Abstract: A device for removing liquid or solid contaminants such as oil or dust dispersed in air in which an air flow is directed through a space formed by a spiral wall in a cyclonic chamber condenses the particles or droplet which drops down into a collection chamber below the cyclonic chamber while the cleaned air passes out through an outlet extending back up through the cyclonic chamber. A baffle plate array is located at the bottom of the collection chamber composed of spaced apart shallowly inclined partially overlapping plates which captures any cyclonic air flow at the bottom of the collection chamber. This removes contaminants which would otherwise accumulate at the center of the bottom of the collection chamber and be entrained in the air exiting the device.

  • Patent number: 8127595
    Abstract: This invention describes a multi-stage pre-concentrator device for use with a detector system. One pre-concentrator stage is detachable and may be used to collect sample remotely from the detection system. The detachable pre-concentrator stage mates with the detector system and can transfer its desorbed sample to another pre-concentrator stage which also incorporates the functions of a sample loop serving as an injection volume to the separation column of an analytical instrument. In one embodiment the fixed pre-concentrator stage serves as a sample loop that preferably integrates suitable valves with sorbent materials onto the same structure to minimise dead volume, maximise sensitivity, improving column loading efficiency, reducing duty cycles and minimising detection system response time.
