    摘要： A supercritical fluid extraction (SFE) system. The SFE system includes a mechanism for providing supercritical fluid for extracting analyte from a sample. The SFE system also includes an extraction vessel and a mechanism for moving the extraction vessel into fluidic communication with the SFE system so that supercritical fluid can flow through the extraction vessel and extract analyte from the sample. Preferably, the SFE system is additionally comprised of a mechanism for holding a plurality of extraction vessels and an extraction chamber assembly. In this design, the moving mechanism selectively moves an extraction vessel from the holding mechanism into the extraction chamber in fluidic communication with the SFE system. Preferably, the SFE system further includes a computer for controlling the functions of the SFE system. The computer, for instance, could automatically and sequentially control the supercritical fluid extractions of the samples within the holding mechanism. The SFE system preferably includes a mechanism for collecting analyte from the fluid with analyte. The collecting mechanism is in fluid communication with extraction chamber assembly and preferably includes a restrictor for controlling the flow of fluid with analyte to the collecting mechanism. The restrictor converts the fluid with analyte from a first supercritical pressure to a second pressure which is less than the first supercritical pressure.

    摘要翻译： 超临界流体萃取（SFE）系统。 SFE系统包括提供用于从样品中提取分析物的超临界流体的机制。 SFE系统还包括提取容器和用于将提取容器移动到与SFE系统流体连通的机构，使得超临界流体可以流过提取容器并从样品中提取分析物。 优选地，SFE系统还包括用于保持多个提取容器和提取室组件的机构。 在该设计中，移动机构选择性地将提取容器从保持机构移动到与SFE系统流体连通的提取室中。 优选地，SFE系统还包括用于控制SFE系统的功能的计算机。 例如，计算机可以自动和顺序地控制保持机构内的样品的超临界流体萃取。 SFE系统优选地包括用于从具有分析物的流体收集分析物的机构。 收集机构与提取室组件流体连通，并且优选地包括限制器，用于控制具有分析物的流体与收集机构的流动。 限流器将具有分析物的流体从第一超临界压力转换为小于第一超临界压力的第二压力。
