    • A method and portable apparatus for self-powered, sensitive analysis of solid, liquid or gas samples for the presence of elements is provided. The apparatus includes a compact sensor system which utilizes a microwave power source and a shorted waveguide to induce a plasma. The microwave power source may be a magnetron or the like. The device includes a portable power supply and preferably includes a portable battery charger. The portable power supply includes a compact generator-internal combustion engine unit. The device can be operated by directly using power from the portable power supply or in a more compact embodiment by using power from batteries that are recharged by a separate portable power supply module. Pulsed microwave operation can be used to reduce average power requirements and facilitate the use of very compact units using batteries. The device is capable of being transported to and from remote sites for analysis by an individual without the need for heavy transportation equipment. A computer may be utilized to control the portable power supply, the battery charger and the microwave power source. The method and apparatus are capable of analyzing samples for the presence of several elements simultaneously using fiber optic guides and a spectrometer system. The apparatus can be contained in a plurality of readily detactable modules to facilitate transportation and field operation.
    • 提供了一种用于固体,液体或气体样品用于元件存在的自供电敏感分析的方法和便携式设备。 该装置包括利用微波功率源和短路波导来诱导等离子体的小型传感器系统。 微波功率源可以是磁控管等。 该装置包括便携式电源,并且优选地包括便携式电池充电器。 便携式电源包括紧凑型发电机 - 内燃机单元。 可以通过直接使用来自便携式电源的电力或通过使用由单独的便携式电源模块再充电的电池的电力在更紧凑的实施例中来操作该装置。 脉冲微波操作可用于降低平均功率需求,并有助于使用非常紧凑的单元使用电池。 该设备能够被运送到远程站点和从远程站点进行分析,无需重型运输设备。 可以使用计算机来控制便携式电源,电池充电器和微波电源。 该方法和装置能够使用光纤引导件和光谱仪系统同时分析几个元件的存在。 该装置可以容纳在多个易于拆卸的模块中,以便于运输和现场操作。

    • A gasification system method and apparatus to convert a feed stream containing at least some organic material into synthesis gas having a first region, a second region, a gas solid separator, and a means for controlling the flow of material from the first region to the second region. The feed stream is introduced into the system, and the feed stream is partially oxidized in the first region thereby creating a solid material and a gas material. The method further includes the steps of separating at least a portion of the solid material from the gas material with the gas solid separator, controlling the flow of the solid material into the second region from the first region, and heating the solid material in the second region with an electrical means.
