Abstract: A sample cell can be designed to minimize excess gas volume. Described features can be advantageous in reducing an amount of gas required to flow through the sample cell during spectroscopic measurements, and in reducing a time (e.g. a total volume of gas) required to flush the cell between sampling events. In some examples, contours of the inners surfaces of the sample cell that contact the contained gas can be shaped, dimensioned, etc. such that a maximum clearance distance is provided between the inner surfaces at one or more locations. Systems, methods, and articles, etc. are described.

Abstract: A spectrometer cell can include a spacer, at least one end cap, and at least one mirror with a reflective surface. The end cap can be positioned proximate to a first contact end of the spacer such that the end cap and spacer at least partially enclose an internal volume of the spectrometer cell. The mirror can be secured in place by a mechanical attachment that may include attachment materials that are chemically inert to at least one reactive gas compound, be thermally stable above at least 120 °C, and be capable of holding an optical axis of the reflective surface in a fixed orientation relative to other components of the spectrometer cell and or a spectrometer device that comprises the spectrometer cell. The mirror can optionally be constructed of a material such as stainless steel, copper, aluminum, alumino-silicate, ceramic, or the like. Related methods, articles of manufacture, systems, etc. are described.
