    摘要: A method and apparatus are provided for pumping gas. The method includes the steps of providing an orifice with an entry diameter that is substantially larger than an exit diameter, imposing a non-uniform electric field between the entry and exit of the orifice and pumping permanent and field induced molecular dipoles through the orifice using the non-uniform electric field wherein the dipoles drift towards a direction of higher field strength within the non-uniform, time-dependent and multi-phase electric field.

    摘要: 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.

    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 self-calibration device and method for a FFET sensor having a thin functional film positioned to detect the presence of at least one specific component in a fluid, a current driven source, a gate and a voltage source applied to said gate, a tub and a drain. An input signal is applied to the gate to produce a measured output signal that is compared to an expected output reference signal. The input signal is selected from controlled voltage pulses to the gate, or the source bias current can be changed. Alternatively, the signal can be a known concentration pulse of the specific component applied to the FFET or a heat source pulse for changing the temperature of the FFET by a small amount.

    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 analyses, drive signals for control, management of wireless signal transmission and reception, processing, and other operational uses of the micro analyzer.

    摘要: An ion pump having conductive electrodes on both sides of an insulator which may form a number of channels. These electrodes may provide electrical discharges which have a corona or cold cathode emission for ionization. The electrodes and the insulator may be layers having openings that form the channels. The openings in one electrode layer may have a sharp-like configuration and the openings in the other electrode layer may have a non-sharp-like configuration. Ions may be predominately in-situ generated proximate to the sharp-like openings and have the polarity of these openings. These ions may induce a fluid flow through the channels of neutral molecules as a result of a force and viscous drag of the ions. The sharp-like openings may have nanotube whiskers or a thin film structure for facilitating an electrical discharge.
