Abstract: A laser spectrometer can be operated for analysis of one or more analytes present in a combustible gas mixture. The spectrometer can include one or more features that enable intrinsically safe operation. In other words, electrical, electronic, thermal, and/or optical energy sources can be limited within an hazardous are of the spectrometer where it is possible for an explosive gas mixture to exist. Methods, systems, articles and the like are described.

Abstract: A spectrometer includes a light source configured to emit a beam along a beam path through a sample volume comprising an analyte. Also included is at least one detector positioned to detect at least a portion of the beam emitted by the light source, and at least one reflector positioned along the beam path intermediate the light source and the at least one detector having a surface roughness greater than a predefined level such as 20 Å RMS.

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.
