Flame Ionization Detector Patents (Class 422/54)
  • Patent number: 10151733
    Abstract: The present disclosure relates to an oxidizer, and related methods, for oxidizing polar modifiers in chromatographic mobile phases. The oxidizer enables the use of flame-based detection in chromatographic separations, such as carbon dioxide based chromatography, which employ polar modifiers, such as methanol. Upon exiting a chromatographic column, the mobile phase containing the polar modifier is flowed through an oxidizer that contains a catalyst to oxidize at least a portion of the polar modifier to a species that does not interfere with the function of the flame-based detector. The oxidizer allows for flame-based detection, such as flame ionization detection, in applications in which a polar modifier with a reduced form of carbon is used.

  • Patent number: 10024768
    Abstract: System, method, and apparatus embodiments characterize potential air emissions during the pig receiver depressurization. The mass flow rate, pressure, and temperature of exhaust gas released from the pig receiver are ascertained using a mass flow meter, pressure gauge, and temperature gauge, respectively. A flow meter and control valve regulate flow of exhaust gas through a sampling line and into a grab sample collection train. The grab sample collection train includes grab sample containers (e.g., piston cylinders, double-ended cylinders, and evacuated canisters) that collect exhaust gas samples over a range of pressures. The exhaust gas samples are used to determine the concentrations of gas components in the exhaust gas over the range of pressures. These concentrations are interpolated and/or extrapolated to provide a concentration versus pressure curve for each identified component in the exhaust gas.

    Abstract: Improved system for gas chromatography wherein use is made of a separation column and a TCD (Thermal Conductivity Detector), characterized in that the outflow from the separation column is ionized, and the ionization takes place upstream of the TCD. The ionization of the outflow from the separation column upstream of the TCD is surprisingly found in many cases to have a favorable effect on the response of the TCD. The sensitivity of the TCD is found in many cases to increase substantially. For ionization purposes use can be made of electromagnetic radiation, ionizing radiation or pyrolysis. The degree of ionization is preferably measured by means of measuring means provided for the purpose. The response of the TCD and the measurement data obtained with the measuring means are found together to give in many cases even more and better information relating to components present in the outflow from the separation column.

  • Patent number: 7976780
    Abstract: Methods and apparatus are provided to measure isotopic characteristics of a number of sample types. Embodiments of the invention combine novel and existing components to produce more accurate isotopic information. Further, embodiments of the invention allow for isotopic readings to be taken and analyzed outside of a laboratory. An example of such an embodiment is an apparatus comprising a combustion furnace; a reactant tube passing through the combustion furnace; an injector coupled to one, or a combination of, the combustion furnace, and reactant tube, to introduce a sample; a laser isotopic measurement device coupled to the reactant tube on the exit end; and a processor electrically coupled to one, or a combination of, the injector, the combustion furnace, the reactant tube, and the isotopic measurement device, in which a carrier gas transports the sample through the apparatus.

  • Publication number: 20110091983
    Abstract: Improved system for gas chromatography wherein use is made of a separation column and a TCD (Thermal Conductivity Detector), characterized in that the outflow from the separation column is ionized, and the ionization takes place upstream of the TCD. The ionization of the outflow from the separation column upstream of the TCD is surprisingly found in many cases to have a favourable effect on the response of the TCD. The sensitivity of the TCD is found in many cases to increase substantially. For ionization purposes use can be made of electromagnetic radiation, ionizing radiation or pyrolysis. The degree of ionization is preferably measured by means of measuring means provided for the purpose. The response of the TCD and the measurement data obtained with the measuring means are found together to give in many cases even more and better information relating to components present in the outflow from the separation column.

  • Patent number: 7837935
    Abstract: Disclosed is a small-sized joint for joining hydrogen gas running route-forming members, which can surely prevent the leakage of hydrogen gas, and a portable hydrogen flame ionization gas detector that can prevent the leakage of hydrogen gas to achieve high safety. The joint comprises a metallic base having an internal space at least one end of which is opened, and a ring-like sealing member composed of an elastic material and arranged at opening edge of the metallic base, wherein a hydrogen gas running route-forming member is fixed in a state inserted into an internal space of the metallic base through the sealing member, and the sealing member is squeezed to gastightly seal the space, whereby one hydrogen gas running route-forming member is removably joined. In the gas detector, the joint is used to form a hydrogen gas running route.

  • Patent number: 7749436
    Abstract: As previous processing of measurement in which gas to be measured containing, as gas components, carbon dioxide 13CO2 and carbon dioxide 12CO2, is introduced into a cell, and in which the intensities of transmitted lights having wavelengths suitable for measurement of the respective gas components, are measured and then data-processed to measure the concentrations of the gas components, the air having a predetermined volume Va is sucked by a gas injection device 21, a gas exhaust valve V6 of a cell 11 is closed and the air stored in the gas injection device 21 is transferred to the cell 11 filled with the air at an atmospheric pressure, thereby to pressurize the cell inside. The pressure thus pressurized is measured as P. The cell volume Vc is subtracted from the product obtained by multiplying the sum.

  • Patent number: 7150780
    Abstract: An electrostatic air cleaning device includes an array of electrodes. The electrodes include corona electrodes connected to a suitable source of high voltage so as to generate a corona discharge. Laterally displaced collecting electrodes include one or more bulges that have aerodynamic frontal “upwind” surfaces and airflow disrupting tailing edges downwind that create quite zones for the collection of particulates removed from the air. The bulges may be formed as rounded leading edges on the collecting electrodes and/or as ramped surfaces located, for example, along a midsection of the electrodes. Repelling electrodes positioned between pairs of the collecting electrodes may include similar bulges such as cylindrical or semi-cylindrical leading and/or trailing edges.
