    • A sampling apparatus collects sample air from a subject such as a person. The apparatus includes a bypass that divides the sample air stream into a bypass portion and a collector portion. The collector portion of the air stream is delivered to a collector, which traps entrained particles. After the sampling cycle concludes, a mechanical conveyor removes the collector from fluid communication with the bypass and transports it to a analyzing unit. A chamber in the unit receives the collector, and a diverter couples the chamber with either of two vapor and/or particle analyzers. During analysis, a heater in the unit heats both the chamber and the diverter. A sample collected from one subject can be analyzed in one of the analyzers while another sample is being collected from another subject. The other analyzer can then be used to analyze the second sample.
    • 采样装置从诸如人的对象收集样品空气。 该装置包括将样品空气流分成旁路部分和收集器部分的旁路。 空气流的收集器部分被传送到收集器,捕集夹带的颗粒。 采样周期结束后,机械传送器将收集器与旁路流体连通并将其传送到分析单元。 该单元中的室接收收集器,并且分流器将室与两个蒸气和/或颗粒分析器中的任一个耦合。 在分析过程中,单元中的加热器加热室和分流器。 从一个受试者收集的样品可以在其中一个分析仪中进行分析,而另一个样品从另一个受试者收集。 然后可以使用另一个分析仪来分析第二个样品。
