A device using needed hydrogen gas flow and electricity for operation obtained from a fuel cell power supply. Also, water generated by the fuel cell may be recycled for hydrogen generation which may be used by the device and in turn expanded by the fuel cell for further electrical power generation. The device may be a gas chromatograph, a fluid calibration mechanism, a flame ionization detector, or the like.

Hydrogen and electrical power generator

A highly sensitive fluid composition analyzer where a fluid may be placed in contact with a very small area on a material sensitized to change color in the presence of a specific type of compound, to be impinged with light. The light reflected, transmitted and/or scattered by the material may serve as input for the analyzer electronics. The fluid may be pre-concentrated prior to being brought in contact with the material. The area on the material may be a spot having an outside dimension of less than one millimeter.

Gas analyzer cassette system

A gas analyzer apparatus includes a device or platform for supporting a predetermined quantity of a reagent capable of reacting with a predetermined gas to cause a detectable change in a characteristic of the reagent, a reservoir adapted to retain the reagent, a dispenser for dispensing a controlled quantity of the reagent from the reservoir to a predetermined position on the device for supporting the predetermined quantity of the reagent, and a detector that detects the presence of the predetermined gas upon the predetermined gas and the controlled quantity of reagent reacting to cause a detectable change in a characteristic of the reagent detectable by the detector, the detector adapted to detect a change in the controlled quantity of the reagent by detecting the change in the characteristic through the predetermined quantity of the reagent.

Gas analyzer apparatus and method of analyzing gases

Embodiments of the present invention relate to a gas sensor comprising a flow channel, a concentration modulator positioned in the flow channel, a gas generator in contact with the flow channel, one or more gas detectors positioned downstream of the concentration modulator and gas generator and a pump.

Self-calibrating sensor

A chemical impedance detector having several electrodes situated on or across a dielectric layer of a substrate. The electrodes may be across or covered with a thin film polymer. Each electrode may have a set of finger-like electrodes. Each set of finger-like electrodes may be intermeshed, but not in contact, with another set of finger-like electrodes. The thin-film polymer may have a low dielectric constant and a high porous surface area. The chemical impedance detector may be incorporated in a micro fluid analyzer system.

Chemical impedance detectors for fluid analyzers

A thermal liquid flow sensor and method of forming same. The sensor has a substrate and one or more sensing elements, disposed on the substrate, for sensing a property of a liquid. The liquid flow sensor, which can be for example a microsensor having a microbrick&#xae; structure, has a hydrophilic layer which is disposed on the substrate and covers the sensing element(s). The hydrophilic layer is preferably formed from a spin on glass material, such as for example a silicate or phosphosilicate. A silicon nitride layer can be disposed on the sensing element(s) and interpose the substrate and the hydrophilic layer. The silicon nitride layer can be oxidized, for example, by means of plasma oxidation or oxygen ion implantation so to form the hydrophilic layer thereon. A variety of other hydrophilic compounds can be utilized to form the hydrophilic layer such as, gold, palladium and diamond like carbon.

Thermal liquid flow sensor and method of forming same

A method of making a plurality of flow sensors is provided, each flow sensor having a substrate with a sensing element and flow channel aligned over the sensing element. The sensing element senses at least one property of a fluid. The flow channel is aligned by one or more guide elements formed in an alignment layer. The flow channel across the sensing area is accurately and precisely aligned due to the guide elements provided at the wafer-level, facilitating reliable, low-cost, and consistent results among multiple flow sensors. The flow sensor is adapted for use in harsh environments.

Method of making a plurality of flow sensors

A micro fluid analyzer that may be highly sensitive, fast and very compact. The analyzer may use sufficiently low power per analysis to be easily implemented with an equivalently small battery pack or other portable power source. There may be energy conservation features in the analyzer, such as optimal adsorber film thicknesses in the pre-concentrator, concentrator and chromatographic separators. There may be special timing of the phased heating elements in the concentrators and separators to further reduce energy consumption. Various kinds of detectors and sensors may be incorporated in the analyzer for achieving low probability for false positives and detection versatility. There may be a controller that provides data acquisition and analyzes, drive signals for control, management of wireless signal transmission and reception, processing, and other operational uses of the micro analyzer.

Phased micro analyzer VIII

A method and apparatus are provided for pumping a gas. The method includes the steps of ionizing the gas, separating the ionized gas into groups of positive and negative ions using positive and negative electric fields and separately pulling the groups of positive and negative ions along a channel using the negative and positive electric fields.

Ion micro pump

Selecting a stationary phase for a fluid analyzer using certain criteria to determine an appropriate material for use in, for instance, a micro fluid analyzer. High absorption of an analyte or sample, low water sorbency and high porosity or permeability of the material may be sought. A selected material may incorporate a toughening agent using a neutral leaving group. A selected material may have a capping agent to promote hydrophobicity. A selected material may be a hydrophobic polymer. The selection of a stationary phase may involve molecular modeling.

Stationary phase materials for micro gas analyzer

A sensor system having an analyte modulator, detector and a pump. The concentration of an analyte sample may be modulated at one time constant. The detector may have an output with a drift at another time constant. The one time constant may be shorter than the latter time constant. The latter time constant may be substantially removed from the detector output with a discriminator. A reservoir may receive high concentrations of analyte from the modulator, before analyte is forwarded to the detector and pump via analyte conveyance lines and valving. The modulation or pre-concentration of analyte in the sensor system may entail shorter times and smaller volumes than those needed by the detector. Such mismatches may be alleviated via accumulation of analyte in the reservoir prior to being forwarded to the detector.

Sensor with an analyte modulator

A microscale planar device for detecting particles under high pressure with high sensitivity. The device may have an anode and cathode with an insulator situated between them. The insulator may have a number of holes, cavities or channels between the anode and cathode. There may be conductive rings at the perimeters of openings of the channels on the anode side of the insulator. These rings may be a part of the anode. An ion may be attracted into one of the channels where it interacts with a gas to result in an avalanche breakdown. The breakdown may be detected by instrumentation connected to the anode and cathode. The lateral and/or longitudinal dimensions of the channels may be such that the device may operate as a detector with ambient air as a gas under its pressure of about one atmosphere.

Microscale gas discharge ion detector

A fire suppression valve includes an RF transmitter which transmits an indication that a closed valve has opened. The transmitter can be implemented as a passive wireless identifier tag energized by a source of wireless signals.

Sprinkler status indicator

A three-wafer channel or column structure for a fluid analyzer. The structure may have a support member, membrane, or support wafer containing heaters and interactive elements. The membrane may have a channel of one wafer facing the interactive element side and a space of another wafer facing the other side. The membrane may have perforations to equalize the pressures on both sides of the membrane. A detector in the membrane may have exposure to both the channel and space for good sensitivity, as the sample may be on both sides of the membrane. The wafers may be bonded with a thin film of non-flowing viscous material. Capillaries may be attached to an inlet and outlet of the channel and be parallel to an elongated dimension of the channel.
