摘要： A headspace sampling system monitors materials in wastewater. The headspace sampling system comprises a sample receptacle that can contain a wastewater sample; a sparger chamber vapor column; a sample receptacle cover assembly that connects the sparger chamber vapor column to the sample receptacle; a sparger tube; at least one sensing device; and at least one analytic device. The sparger tube and the sample receptacle define a headspace. The sparger chamber vapor column is in communication with the sample receptacle and is closed by a sparger chamber vapor column cover at a second end that is opposed to the sample receptacle. The sparger tube extends into the sample receptacle and the wastewater sample in the sample receptacle. The sparger tube is connected to a source of inert gas at a first end opposed to the sample receptacle and comprises a dispersion device at an end opposed to the first end. The sensing device is disposed in the headspace sampling system in the headspace. The analytic device in communication with the least one sensing device. Inert gas can flow through the sparger tube into the wastewater sample to separate materials from the wastewater, the sparged materials entering the headspace of the headspace sampling system. The sparged materials are sensed by the sensing device thus providing material signal characteristics, which can be analyzed by the analytic device to determine characteristics of the material from the material signal characteristics and provide information about the characteristics of the material.

摘要： The present invention comprises a system and method for extracting and conveying sampling gases from a remote location for component and quality testing by a gas-sampling device by use of a venturi-based manifold that moves a volume of motivating gases to create a venturi effect. The venturi-based gas sampling manifold includes an air extractor assembly having an inlet port with an associated inlet valve for selectively interrupting the flow of gas through the inlet port, a venturi connected on one end to a venturi jet and on the other end to a venting horn, and a plenum extending from the inlet port to the available end of the venturi. The present system further includes a sampling manifold assembly having a manifold in which the plenum of the air extractor assembly is carried, one or more manifold ports with associated manifold port valves for selectively adjusting the flow rate through the manifold port, and one or more sampling ports. In operation, the venturi air extractor generates a vacuum according to Bernoulli's equations. Selective opening of the manifold ports on the manifold along with the application of vacuum draws sampling gases from remote locations through probes and the associated connecting hoses to the manifold. Once the suspect sampling gases, drawn through the appropriate probe, fill the manifold, the operator eliminates the vacuum and the drawn sample gases are available for testing at the sampling port. After testing, the operator reapplies the vacuum and flushes the sampling gases.

摘要： A method and apparatus for collecting outgassed compounds during a dynamic headspace outgassing test includes placing a component to be tested within a sample container formed from an inert material and placing the container within an oven to heat the component. A gas inflow line directs a flow of inert gas to envelop the component within the sample container and mix with the compounds outgassed from the component. An outflow line formed from an inert material directs the mixture of inert gas and outgassed compounds from the sample container to a trap which separates the inert gas from the outgassed compounds and retains the outgassed compounds for further analysis. The sample container includes a body and a top formed from an inert material and fasteners securing the body and top together to seal the component within an interior chamber of the container.

摘要： A new high flow rate sampling device and methods for measuring fugitive gas emissions are provided. The high flow rate sampler comprises an air mover connected to a flexible hose for drawing in air near a process component, such as a pump, compressor seal, flange, or pipe thread connection. A second sample hose draws air from the opposing side of the process component at a flow rate low enough not to affect capture of the leak by the first sample hose. Air measured from the first sample hose will contain fugitive emissions from the process component being measured, as well as from other process components. Air measured from the second sample hose will contain only fugitive emissions from surrounding process components and can then be subtracted from the measurement from the first sample hose to obtain the leak rate from the process component in question.

摘要： A method for collectively sampling a plurality of cargo items for contaminants such as chemical residues. The items are placed in a generally airtight chamber and agitated physically to release particulates and vapors from the surfaces and interior of the items. The methods of physical agitation include vibrating the items, and pressurizing and depressurizing the chamber, with the pressurizing being done by introducing bursts of high pressure air into the chamber and by directing jets of high pressure air at the cargo. Optionally, the high pressure air may be heated or mixed with solvent vapors. This physical agitation drives particulates and vapors of contaminants into suspension in the air in the chamber. Air withdrawn during depressurization is passed through a collection system to collect the particulates and vapors for subsequent analysis.

摘要： The gas sample device structure has a housing with a continuous normally vertical sidewall, closed top and an open bottom. Buoyant elements are secured to the housing to maintain its vertical position in a body of liquid livestock waste. A normally closed compartment is located on the top of the housing. A partition is located within the closed compartment to divide it into first and second subcompartments. An opening is provided in the closed top of the housing to allow gases from liquid manure in the housing to move into the first subcompartment. One or more hollow gas detection tubes are mounted in the second subcompartment and have a first open end in communication with the interior of the first subcompartment to receive gases from within the first compartment. The method of the invention involves placing the housing in a liquid manure lagoon so its buoyancy is maintained by the buoyancy elements, but the lower portion thereof is submerged in the liquid manure. The gases rise from the liquid into the upper end of the housing and through a suitable opening into a closed compartment on top of the housing where the gases are caused to move through gas detection tubes for a period of time.

摘要： An inspection system for sampling and determining the presence of residues of contaminants within plastic materials to be recycled from used plastic materials such as plastic beverage bottles or plastic food containers includes a chemical sniffing apparatus, or alternatively an optical scanner, for detecting the contaminants as the plastic materials are rapidly moved along a conveyor past a series of stations. Recycled food or beverage bottles are fed through a shredder in-line with the conveyor and the shredded plastic material from the bottles is fed to a washer. The bottles and shredded material may be tested for contaminants at any location in an in-line process. In one exemplary system first the bottles are tested prior to entry into the shredder in order to remove bottles containing gross contaminants. Second the shredded material emerging from the shredder is immediately tested for contaminants at an elevated temperature caused by the shredding process and contaminated materials are separated or sorted out from the uncontaminated material. Third, the materials are again tested for contaminants as they emerge from the washer once again taking advantage of the elevated temperature of the materials which is conducive to the emission of vapors of the contaminants. Contaminated materials are again sorted from the uncontaminated supply of materials to be used for the fabrication of new plastic food or beverage bottles.

摘要： A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators. A high speed gas chromatograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected. A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives. Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses. The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection.
