Disclosed is a spectroscopic device, system, and method for measuring the concentration of one or more molecular species of interest in a gas, liquid or solid sample, where the device may be portable, may be commercially manufactured, and/or may be adapted to existing systems and/or integrated with new systems to provide optical gas sensing for such systems. The disclosed devices, systems, and methods can be particularly useful in monitoring the purity of, e.g., a certain gas species, including determining whether a gas mixture contains certain gas species above a set concentration limit.
