    Abstract: A frequency registration deviation is quantified for a field spectrum collected during analysis by a spectroscopic analysis system of a sample fluid when the spectroscopic analysis system has deviated from a standard calibration state. The field spectrum is corrected based on the frequency registration deviation using at least one spectral shift technique, and a concentration is calculated for at least one analyte represented by the field spectrum using the corrected field spectrum. Related systems, methods, and articles are described.

    Abstract: 在含有一或多種可能具有干擾吸光光譜特徵之背景分析物的氣體混合物中,可以藉由在目標波長下補償背景分析物之吸收度,計算目標分析物之濃度,以定量該目標分析物。可在選擇用於定量該背景分析物濃度的參考波長下,測量吸收度。使用背景氣體調節係數或函數,在參考波長下測量的吸收度可用來計算目標波長下因背景分析物所造成的吸收度,並因此補償該背景吸收度,以更精確地即時計算或接近即時計算該目標分析物濃度。藉由採用一或多種額外的參考波長,可視情況補償額外背景分析物。

    Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

    Abstract: At least one light source is configured to emit at least one beam into a sample volume of an absorbing medium. In addition, at least one detector is positioned to detect at least a portion of the beam emitted by the at least one light source. Further, at least one beam modification element is positioned between the at least one detector and the at least one light source to selectively change at least one of (i) a power intensity of, or (ii) a shape of the beam emitted by the at least one light source as detected by the at least one detector. A control circuit is coupled to the beam modification element. Related apparatus methods, articles of manufacture, systems, and the like are described.
