  • Patent number: 7718434
    Abstract: The diffusion coefficients and relaxation times of mixtures of alkanes follow simple scaling laws based on the chain length of the constituents and the mean chain length of the mixture. These scaling laws are used to determine chain sizes in a mixture from the distribution of the diffusion coefficients. These scaling laws can be used to determine the mean chain lengths (or chain lengths) of a sample (alkanes or mixtures of alkanes) and therefore the constituents of the sample.

  • Patent number: 7435597
    Abstract: The present invention is directed to novel assays for zero-valent transition metals. The novel assays of the present invention are generally methods or processes for quantitatively and/or qualitatively evaluating the presence of zero-valent transition metals on and/or within samples. Such assays generally involve a digestion process whereby the sample is exposed to carbon monoxide. Transition metals, if present in or on the sample and if contacted by the carbon monoxide, are extracted by the carbon monoxide as metal carbonyl species, the presence of which confirms the presence of transition metals. Such novel assays have enormous predictive power in oil and gas exploration.

  • Patent number: 6319717
    Abstract: The present invention is a one-step thermal method for analyzing the acid-base content of earth samples, specifically mine overburden samples. By using a low oxygen concentration, preferably about 3%, the transition metal carbonates in the sample decomposed to produce carbon dioxide at a lower temperature than the alkaline earth metal carbonates. In contrast, alkaline earth metal carbonates decompose at approximately the same (higher) temperature regardless of the oxygen concentration. Any oxidizable sulfur forms present in the sample are also oxidized by using this oxygen concentration so that only one experiment is required to obtain the carbonate and sulfur contents of the sample.

  • Patent number: 5561066
    Abstract: Organic and inorganic contaminants of an environmental sample are analyzed by the same GC-MS instrument by adding an oxidizing agent to the sample to oxidize metal or metal compounds to form metal ions. The metal ions are converted to chelate complexes and the chelate complexes are extracted into a supercritical fluid such as CO.sub.2. The metal chelate extract after flowing through a restrictor tube is directly injected into the ionization chamber of a mass spectrometer, preferably containing a refractory metal filament such as rhenium to fragment the complex to release metal ions which are detected. This provides a fast, economical method for the analysis of metal contaminants in a sample and can be automated. An organic extract of the sample in conventional or supercritical fluid solvents can be detected in the same mass spectrometer, preferably after separation in a supercritical fluid chromatograph.

  • Patent number: 5385827
    Abstract: A method of geochemical prospecting where samples of soil, sediment and rock in a geological area are collected and each sample is contacted with a leach solution of water, glucose and glucose oxidase. The oxidase acts upon the glucose to produce gluconic acid and hydrogen peroxide. The leach solution reacts with manganese dioxide carrying trace metal elements and compounds in the samples to produce a leach reaction solution. The leach reaction solution and the residue of the said sample are separated, and the leach reaction solution is analyzed to determine the trace metal content present. From the analysis, the mineral content of the geological area is predicted.

  • Patent number: 4565786
    Abstract: A method and apparatus has been provided to locate a subterranian precious ore and/or sulfide body from which mercury gas is emanating. The apparatus includes an inverted plastic drinking cup from which a mercury-free silver wire is suspended from its end. This is accomplished by inserting the end of the wire into a foam insulation disk located in the bottom of the inverted cup. Alternatively, wire may be attached within a cap of a storage vial. The cap has an adhesive on the outer surface which adheres it to the bottom of the cup, whereupon the vial is removed from the cap to expose the wire. A foil disk is placed on the outside of the bottom of the cup. A plurality of cups are buried in the ground forming a dead air space around the wire, for a period of weeks wherein any mercury-vapor in the ground in the area of the cup is adsorbed by the wire. These cups are arranged in a predetermined array and are subsequently located by means of a metal detector which can detect the metal foil on the cups.
