Abstract: A plasma-based detector using optical spectroscopic techniques for analysing the constituents of gas samples are provided. The detector includes a plasma-generating mechanism and a plasma-localizing mechanism. Electron-injecting electrodes may be provided in the plasma chamber of the detector. A Pressure control mechanism as well as a doping module may optionally be included. In accordance with some implementations, the collection, detection and analysis of light extracted from the plasma may enable one or more of various operation modes, such as an emission mode, an absorption mode, and indirect detection mode or a constant emission mode.

Abstract: Systems and methods for measuring the isotope ratio of one or more trace gases and/or components of gas mixtures such as different gas species present in a gas mixture. The system includes a resonant optical cavity having two or more mirrors and containing a gas, the cavity having a free spectral range that equals the difference between frequencies of two measured absorption lines of different gas species in the gas, or of two different isotopes, divided onto an integer number. The system also includes a continuous-wave tunable laser optically coupled with the resonant optical cavity, and a detector system for measuring an absorption of laser light by the gas in the cavity. The detector system includes one of a photo-detector configured to measure an intensity of the intra-cavity light or both a photo-acoustic sensor configured to measure photo-acoustic waves generated in the cavity and a photo-detector configured to measure an intensity of the intra-cavity light.

Abstract: Described herein is a spectroscopic system and method for measuring and monitoring the chemical composition and/or impurity content of a sample or sample stream using absorption light spectroscopy. Specifically, in certain embodiments, this invention relates to the use of sample pressure variation to alter the magnitude of the absorption spectrum (e.g., wavelength-dependent signal) received for the sample, thereby obviating the need for a reference or ‘zero’ sample. Rather than use a reference or ‘zero’ sample, embodiments described herein obtain a spectrum/signal from a sample-containing cell at both a first pressure and a second (different) pressure.

Abstract: The invention concerns a gas analyzer comprising: a measuring volume (2), a radiation source (1) for providing a beam to pass said measuring volume; a heat sink (16) for said radiation source; at least one thermal detector (3) having a hot junction within a support structure and receiving the radiation and a cold junction for reference within the same support structure and protected from said radiation; at least one optical bandpass filter (9) between said hot junction and said radiation source; and a thermal mass (11), which is formed of a material having high thermal conductance. The thermal mass has a cavity with a bottom step (34) and a rim (32), and a first length therebetween. The support structure has a frontal edge (35) and a base plate lip (33), and a second length therebetween. There is a radial gap between the thermal mass and the support structure. Press means urge said support structure in the cavity, whereupon a more efficient thermal contact is either between said frontal edge and said bottom step, or between said base plate lip and said rim. A first thermal barrier (17) is between the heat sink and the thermal mass, and a second thermal barrier (22) surrounds the thermal mass. A shield (19) formed of a material having high thermal conductance covers said second thermal barrier and is in thermal contact with said heat sink.
