    摘要: A low power preconcentrator for use in micro gas analysis, such as gas chromatography, and a system that employs the preconcentrator is disclosed. The preconcentrator includes a reservoir that comprises a heater membrane and elements coated at least partially with an adsorbent, and ports for receiving and discharging an analyte in communication with the reservoir. At least a portion of the reservoir (e.g., a cap) is made of a material having a thermal conductivity less than about 100 W/(m·K) and/or the heater membrane is made of a material that has a temperature difference less than about 75° C. when heated. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.

    摘要: A high-temperature pressure sensor is provided. The sensor includes a quartz substrate with a cavity etched on one side. A reflective coating is deposited on at least a portion of the cavity. The sensor further includes a ferrule section coupled to the quartz substrate with the cavity therebetween. The cavity exists in a vacuum, and cavity gap is formed between the reflective metal coating and a surface of the ferrule. The sensor also includes an optical fiber enclosed by the ferrule section and extending from the cavity gap to an opposing end of the ferrule section and a metal casing surrounding the ferrule section and the quartz substrate with an opening for said optical fiber extending therefrom. The pressure applied to the quartz substrate changes the dimensions of the cavity gap and a reflected signal from the reflective coating is processed as a pressure.

    摘要: A microfluidic device with a vertical injection aperture is provided. The microfluidic device comprises a separation channel, an injection aperture disposed adjacent to and in fluid communication with the separation channel. The microfluidic device further comprises a semi-permeable filter disposed adjacent to the injection aperture, wherein the filter is configured to preconcentrate a sample in the injection aperture to form a preconcentrated sample plug during an injection operation, and wherein the sample plug flows downwardly from the injection aperture to the separation channel during an electrophoresis operation.
