  • Patent number: 8833140
    Abstract: Analytes are rapidly desorbed from a carbonaceous sorbent powder with improved quantitation and reduced analyte re-adsorption, thermal degradation, and rearrangement. The sample is distributed in a thin layer onto a desorption surface within a chamber. The layer can be a monolayer. Heating light irradiates the sample through a window, directly and rapidly heating the sample while the desorbed analytes diffuse into a vacuum or are removed by a carrier gas. Finally, the sorbent is flushed from the chamber by a transport gas. The desorption surface can be an inner surface of the window, or a surface of a porous frit that divides the chamber into two sections. The frit can be stainless steel or glass. The carrier gas can be helium, argon, or carbon dioxide. The light source can be a tungsten halogen lamp. A heater can control the chamber temperature according to a heating profile.

  • Patent number: 8807110
    Abstract: A system and method for sampling fluid from a top land piston crevice of a reciprocating piston engine. Access into the crevice is via a length of tubing inserted into a bore through the piston wall. Two valves, first a relief valve and then a piloted check valve, operate together to capture a sample of fluid from the crevice at a time just before TDC of the piston on its compression stroke. The sampled fluid flows from the check valve into a sample container. The valves further cooperate to close fluid communication from the crevice after a sample is taken, which allows the engine to operate normally.

  • Publication number: 20140223994
    Abstract: A device and method for contamination-free transfer of samples is described. The device comprises an elongated member having an internal cavity and pressure-sensitive region. The internal cavity is in communication with at least a first open end of the elongated member. The pressure-sensitive region is disposed at a first distance from the first open end thereby forming a sampling portion of the device. The portion between the pressure-sensitive region and the second end forms a handling portion of the device. The pressure-sensitive region provides a stress concentration that increases the sensitivity to pressure. The device is used by contacting a sample with the first open end thereby causing sample to be received into the internal cavity of the sampling portion. The device is then inserted into a receiving container for use in the desired chemical analysis instrument.

  • Patent number: 8794594
    Abstract: Plungers and plunger assemblies for a diaphragm-sealed valve are provided. Each plunger is adapted to be received in a passage of the valve body and includes a base member and an upper member having a longitudinal play in this passage with respect to the base member. A resilient middle element is provided between the upper and base member. The base member is connected to a plunger actuating mechanism within the valve body. Optionally, the upper member may be self-aligning within the passage. The plunger can be used to compensate for temperature variations experienced by the valve in use.

  • Patent number: 8776576
    Abstract: A gas chromatography device adapted for detecting leakage of hydrogen gas without using an air pump and long piping is provided. The gas chromatography device includes: a column oven having a housing, a column disposed in the housing, and a heater heating air in the housing; a sample vaporization chamber supplying a sample to an inlet end of the column; a carrier gas supply section supplying a carrier gas to the sample vaporization chamber; a detector connected to an outlet end of the column; a controller controlling the heater and the carrier gas supply section; and a hydrogen gas detecting sensor. The carrier gas is hydrogen gas. A through hole is formed in the housing and a material that allows hydrogen to pass through but does not transmit heat is disposed in the through hole. The hydrogen gas detecting sensor is disposed near the through hole outside the housing.

  • Patent number: 8738301
    Abstract: The present invention relates to a method for quantitatively analyzing gases as a monitor for on-load tap changers. The general inventive concept lies in selecting particular characteristic gases allowing an indirect subsequent association and a dimension for aging effects, excessive discharge, and/or heating of the on-load tap changer; measuring said characteristic gases, formed during the operation of the tap changer in the insulating oil thereof, at particular time intervals; forming indicative quotients from the measured values of the defined gases, said quotients allowing direct conclusions about aging effects, excessive discharge, and/or heating; displaying trends from a comparison of the currently derived value of each quotient to the most recently derived value for the same quotient; and inferring warnings for aging effects, excessive discharge, and/or heating if the corresponding quotients tend to change significantly over time or in the course of the switch changes made.
