    Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer (405) has an optical element (950) that is positioned with respect to the axis of incident IR radiation such that it passes nearly all of the IR energy within a narrow band pass to one detector (540) and reflects nearly all of the IR energy outside the narrow band pass to another detector (535). Thus, the optical element (950) simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR radiation within a band pass and reflects nearly all the IR radiation outside the band pass. Additionally, the separation of the incoming energy can be achieved without an extended roll off. This allows using a reference transmission band that is very close to the absorption band of the gases of interest. It more specifically allows using a reference transmission band that is located between the absorption bands for hydrocarbons and carbon dioxide in an infrared analyzer that uses beam splitters.

    Abstract: The improved sample chamber includes an elongated hollow tube (12) closed at one end (14) and having specularly-reflective inwardly facing surfaces (16). A source (26) of radiation and a detector (28) of radiation are mounted side by side in the open end of the hollow tube, both facing the closed end. A plurality of filtering apertures (20) are formed in the tube (12), and each aperture is covered by a sheet (22) of a semipermeable membrane that serves to prevent airborne particles larger than a predetermined size from entering the chamber while not interfering with the free diffusion of the gas to be measured into and out of the chamber. The use of an elongated hollow tube that is closed at one end results in no loss in the efficiency with which the radiation is conducted from the source to the detector while decreasing the external length of the chamber by 50 percent.

    Abstract: 형광 분석 시스템은, 광을 유체의 흐름으로 방출하도록 구성된 광원, 유체의 흐름으로부터의 형광 방출들을 검출하도록 구성된 검출기, 및 온도 센서를 갖는 센서 헤드를 포함할 수 있다. 시스템은 또한, 센서 헤드가 삽입될 수 있는 캐비티를 정의하는 하우징을 포함하는 흐름 챔버를 포함할 수 있다. 일부 예시들에서, 하우징은, 유체의 흐름이 하우징으로 진입할 때, 유체의 흐름이 적어도 광원과 검출기에 인접하여 통과하는 메이저 스트림 및 온도 센서에 인접하여 통과하는 마이너 스트림으로 나뉘도록, 구성된다. 이러한 흐름 챔버는, 연속적인 또는 반-연속적인 온라인 동작에 수반되는 고체 입자들의 증강(build-up), 에어 록(air lock)들의 발생, 또는 다른 흐름 문제들을 억제하면서, 상이한 센서들의 컴포넌트들을 지나가도록(past) 유체를 지향시킬 수 있다.
