    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: An optical spectrometer having a multi-wafer structure. The structure may be fabricated with MEMS technology. The spectrometer may be integrated with a fluid analyzer. A reflective grating such as a diffraction or holographic grating situated on the circumference of a Rowland circle along with a point of light emission and a detector may be a configuration of the spectrometer. Some configurations may use an external light source where the light may be optically conveyed to the point of emission on the circle. There may be a Raman configuration where an interaction of light with a sample or an interactive film of a channel in a fluid analyzer is the point of light emission for the spectrometer. In some configurations of the spectrometer, the grating and/or the film may be reflective or transmissive.

    摘要: A differential microdischarge detector system. The system comprises two microdischarge detectors (MDDs). One of the MDDs is connected to receive sample analytes to be measured, while the other MDD is connected to receive a reference sample that contains interfering gases and none or a much lower concentration of the sample analytes to be measured. The outputs of the two MDD's are fed to a circuit that generates either a difference or a ratio between the measurements of the two MDDs. In addition, the current, impedance or voltage across the electrodes of the two MDDs may be measured and processed to generate either a difference or a ratio signal, thus obtaining additional information about the sample gas analytes.

    摘要: A system for effecting a soft or gentle ionization technique to avoid fragmentation of analyte molecules provided to a micro mass spectrometer for analysis. To ionize the analyte molecules, the system may be based on proton transfer reaction (PTR) for ionization, UV light to generate either positive or negative ions, or E-field ionization. For example, with PRT, there may be a water generator for providing H2O to an ion generator. H3O+ may be provided by the generator to a charge transfer reactor that brings a stream of H3O+ molecules together with analyte molecules. Then, H+ atoms may be transferred from the H3O+ molecules to the analyte molecules without breaking up or fragmenting the respective analyte molecules. The ionized molecules may be provided to a micro mass spectrometer for analysis.
