  • Patent number: 10041864
    Abstract: Embodiments of the invention collect solid, vapor, and/or biological components of the air in air-sampling cartridges that are then transported to an off-site location by pneumatic pressure. Operation proceeds by first collecting a sample of air in an air-sampling cartridge in a sampling position, then advancing a cartridge assembly to move the now-used sampling cartridge into a transport position while simultaneously moving an unused sampling cartridge into the sampling position, and finally using pneumatic pressure to push the used sampling cartridge in the transport position to an off-site location via a transport tube. The sampling operation can begin again while the transport operation is in still in progress. These operations can be pre-programmed locally or triggered by remote communication. Continued operation is possible due to a plurality of unused air-sampling cartridges retained in the cartridge assembly.

  • Publication number: 20140157913
    Abstract: An inlet apparatus is disclosed. The apparatus may include a first conduit for sampling, and a second and third conduit for directing flow throughout the inlet apparatus. Flow may be induced in two opposite directions through the second conduit, which affect the flow of gas through the first conduit for sampling. The various conduits of the apparatus may be connected to a device for inducing flow in different directions. The duration of the flow in a particular direction affects the amount of sample gas that enters a detection device.

  • Publication number: 20140130615
    Abstract: A sampler including an ejector and a sample channel extending to the ejector, which are placeable in a mixture of particles of a solid and a medium, the medium being a gas and/or a liquid. The ejector includes at least one inlet and an outlet. The ejector takes a mixture sample by using vacuum via the inlet and discharges it via the outlet so as to make the mixture sample flow from the inlet towards the outlet. The sample channel takes a desired measuring sample from the mixture sample flowing in the ejector, the solid particles and the medium being at least partly separable from one another in the ejector on the basis of the flow and inertia in the mixture sample.

  • Patent number: 8720287
    Abstract: The gas trap collects formation gases from oil well fluid flow in real time. Gases are released by the fluid when agitated by an agitating pipe which stirs the fluid flow; the gases are then collected and separated from the fluid to be analyzed. The gas trap does hinder the flow of formation cuttings in the drilling fluid flow line, but allows the formation cuttings to flow around the agitator pipe and out to the sample box.

  • Publication number: 20140096623
    Abstract: Apparatus for a cotton sample acquisition and tracking system. The system includes a loading station in which a pair of primary sample halves are loaded in a carrier. The primary samples are identified and transported to a sub-sample station that extracts a sub-sample from the primary sample. The sub-samples are conditioned and transported to various testing stations. The primary samples are transported via a conveyor system. The sub-samples are transported through a pneumatic system. The sub-sample station advances the primary sample against a pick drum that pulls tufts from the primary sample. The tufts flow through a cotton containment system into an indexer that collects, conditions, and routes the tufts as a sub-sample. The sub-samples are staged in a carousel for continued conditioning and storage until the test equipment is ready to process the sub-sample.

  • Publication number: 20140083173
    Abstract: A fluid transfer device transfers a fluid from a first fluid channel with a first cross-sectional area into a second fluid channel with a second cross-sectional area, larger than the first cross-sectional area. The fluid transfer device includes a fluid inlet interface at which the fluid is transferable from the first fluid channel into the fluid transfer device; an inlet branch configured to split the fluid from the first fluid channel into multiple inlet branch channels; multiple outlet branches, each of which is configured to split the fluid from the inlet branch channels into respective outlet branch channels; and a fluid outlet interface configured to transfer the fluid in the outlet branch channels into the second fluid channel. The inlet and output branches and branch channels are disposed such that the fluid exits from the fluid outlet interface, distributed in a two-dimensional manner across the second cross-sectional area.

  • Patent number: 8652640
    Abstract: The present invention includes an article of manufacture or device, or related system, comprising a heterogeneous surface for selective analyte sensing or separation. Such an article can comprise a surface member and a plurality of spaced components extending therefrom and coupled thereto, such a surface member and spaced components providing a surface heterogeneity selected from different electrostatic interactions, different non-electrostatic interactions and a combination of such interactions, such that the interactions are at least partially sufficient for selective analyte interaction and/or separation. Each such component extension can be of a nanometer dimension about the Debye length of a medium comprising an analyte particle exposed to such a surface. An analyte particle, optionally of a mixture of particles, can be dimensioned from about 30 nm to 20 ?m.

  • Publication number: 20140033805
    Abstract: The present invention provides novel, simple and reliable methods for extraction of fat soluble vitamins (FSVs) from a sample matrix obtained from food products (e.g., vitamin-enriched foods and fortified food matrices) or biological samples. In certain aspects, the invention provides solid phase extraction (SPE) methods. In certain embodiments, the invention relates to two-step elution methods, which provide excellent recovery of all fat-soluble vitamins from complicated food matrices (such as, vitamin-enriched foods and fortified food products) or biological samples in a simultaneous manner. In certain embodiments, the invention uses OASIS® materials as sorbent beds for separating and/or extracting FSVs from the sample matrix.

  • Publication number: 20140020456
    Abstract: A method of separating petroleum samples containing a hydrocarbon-soluble elemental species of interest to facilitate analysis of an elemental and/or isotopic signature. A petroleum sample is mixed with a demulsifier and separated, for example by centrifuging, into one or more intermediate organic fractions. The intermediate organic fraction(s) are mixed with a solvent such as water and a second demulsifier, then separated into one or more prepared organic fractions and one or more solvent-based fractions. Some or all of the resulting fractions are then stored for possible further processing. Optionally, the petroleum sample may be spiked with one or more of an organic standard and an inorganic standard, and the solvent may likewise be spiked with an inorganic internal standard, to facilitate later analysis.

  • Publication number: 20140007709
    Abstract: A specimen kit having a tiny chamber is disclosed for a specimen preparation for TEM. The space height of the chamber is far smaller than dimensions of blood cells and therefore is adapted to sort nanoparticles from the blood cells. The specimen prepared under this invention is suitable for TEM observation over a true distribution status of nanoparticles in blood. The extremely tiny space height in Z direction eliminates the possibility of aggregation of the nanoparticles and/or agglomeration in Z direction during drying; therefore, a specimen prepared under this invention is suitable for TEM observation over the dispersion and/or agglomeration of nanoparticles in a blood.

    Abstract: A device for sampling chemical compounds from fixed surfaces and related methods are disclosed. The device may include a vacuum source, a chamber and a sorbent material. The device may utilize vacuum extraction to volatilize the chemical compounds from a fixed surface so that they may be sorbed by the sorbent material. The sorbent material may then be analyzed using conventional thermal desorption/gas chromatography/mass spectrometry (TD/GC/MS) instrumentation to determine presence of the chemical compounds. The methods may include detecting release and presence of one or more chemical compounds and determining the efficacy of decontamination. The device may be useful in collection and analysis of a variety of chemical compounds, such as residual chemical warfare agents, chemical attribution signatures and toxic industrial chemicals.
