摘要： A process gas analyzer and method for analyzing a process gas carried in a plant section, wherein light from a light source is passed through the process gas and detected via a detector, evaluated in an evaluation unit to produce an analysis result with respect to the absorption in the process gas, where chambers or purging pipes, present between the light source and the plant section and also between the detector and the plant section, are flushed with a purge gas to analyze the process gas, and where the volume flow rate of the purge gas is periodically modulated and the effect of the purge gas on the analysis result is determined based on changes in the detected absorption caused by the modulation and removed from the analysis result to enable a high degree of compensation for measurement errors caused by the purging.

摘要： Absorption spectrometer and method for measuring the concentration of a gaseous component of interest in a measurement gas, wherein to compensate influence of changes in an optical path length in the absorption spectrometer on a measured result, light from the laser is modulated with at least one pilot frequency in the MHz range, the measurement signal is analyzed in a phase-sensitive manner for the pilot frequency, phase information obtained during this analysis is compared with phase information obtained during calibration of the absorption spectrometer, where the measured result is corrected as a function of the difference between the two items of phase information. Alternatively, light from the laser is modulated with two pilot frequencies, where signal components contained in the measurement signal with the pilot frequencies are detected in a phase-sensitive manner and the difference between the phase information of the two signal components obtained in this operation is analyzed.
