A sample handling apparatus/technique/method for a material analyzer, which provides active, variable concentration of a sample, using a measurement marker introduced into the sample, to measurably concentrate an analyte in a liquid (e.g., water) sample. Active, variable concentration allows otherwise lower level analytes to be concentrated in a measurable way. This enables measurements at higher (e.g., concentrated) levels, which can be extrapolated to obtain their lower, original levels based on the concentration level&#x2014;measured using the introduced marker as a guide. The sample handling apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, usable during both during the concentration and analyte measurement.

Active, variable sample concentration method and apparatus for sub-ppb measurements and exemplary X-ray analysis applications thereof

An x-ray analysis system having an x-ray engine with an x-ray source for producing an x-ray excitation beam directed toward an x-ray analysis focal area; a sample chamber for presenting a sample stream to the x-ray analysis focal area, the analysis focal area disposed within a sample analysis area defined within the chamber; an x-ray detection path for collecting secondary x-rays and directing the x-rays toward a detector; an x-ray transparent barrier on a wall of the chamber through which the x-rays pass; and a blocking structure partially blocking the sample analysis area, for creating sample stream turbulence in the sample analysis area and over the barrier. The blocking structure may be disposed asymmetrically about a central axis of the x-ray analysis focal area and/or the sample analysis area; and may be a rounded pin. A heating element may be used to heat the sample stream for improving flow.

Sample viscosity and flow control for heavy samples, and X-ray analysis applications thereof

A sample handling apparatus/technique/method are provided for a material analyzer, including: a sample cell insert for carrying sample to and from a sample focal area of the analyzer; a removable sample carrying device for providing sample to the cell insert; and an actuator to flow sample from the carrying device to the sample cell insert. The removable sample carrying device may be a syringe, and the actuator pushes a plunger of the syringe to expel the sample to the sample cell insert. The sample cell insert may be mounted onto a sample cell, the sample cell being insertable into the analyzer for sample analysis. The sample handling apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, wherein the x-ray excitation and/or the x-ray detection path define the sample focal area.

Non-homogeneous sample handling apparatus and X-ray analyzer applications thereof

Disclosed herein is a structural sheet includes an energy storage density that is greater than 10-mWh/ft2 and is capable of withstanding greater than 5-KPa stress under at least 5% strain. Further provided is an energy storing structural sheet comprising an electrically conducting current carrying layer that is print formed over a sub assembly that comprises a separator, a foundation, an electrode, and a current bus.

Compliant energy storing structural sheet

Fuel feed systems capable of providing substantially consistent flow of fuel to a fuel cell and also capable of tolerating varying pressures from a reservoir (also referred to as fuel supply or fuel cell cartridge) and the fuel cell while maintaining substantially consistent control flow to the fuel cell are disclosed.

Fuel cell feed systems

The invention generally relates to a fuel processor design and a method for manufacture. In one aspect of the invention, a fuel processor assembly has a first plate and a second plate that are mated to form a plurality of reactor housings and channels to direct the reactants. At least one of the first and second plates has an inlet orifice feature adapted to receive a hydrocarbon stream, and at least one of the first and second plates has an outlet orifice feature adapted to exhaust a reformate stream. In some embodiments, a third plate and a fourth plate can be mated to enclose the first and second plates so that a coolant can be circulated between an external surface of the first and second plates and an internal surface of the third and fourth plates.

Fuel processor design and method of manufacture

A fuel cell system includes a fuel cell stack, an enclosure housing the fuel cell stack and a blower. The blower is located inside the enclosure and is adapted to draw air from inside the enclosure to produce an air flow through the fuel cell stack and establish a negative pressure inside the enclosure with respect to a region outside of the enclosure.

A connector includes an outer sleeve and an inner sleeve. The outer sleeve has an inner wall and a pair of juxtaposed slots. The inner sleeve has an outer surface with a first groove and a second groove defined therein. A sealing member is located in the first groove of the inner sleeve. The sealing member provides a continuous seal between the inner wall of the outer sleeve and the outer surface of the inner sleeve when the inner sleeve is mated within the outer sleeve. A retaining member is configured to engage the pair of juxtaposed slots, of the outer sleeve, and the second groove, of the inner sleeve, when the inner sleeve is mated with the outer sleeve. The retaining member restricts the longitudinal movement of the inner and outer sleeves in relation to one another.
