Abstract

An active method of differential optical absorption spectroscopy (DOAS) is an effective tool for long-path measurements of atmospheric gases and impurity. A model of a portable non-volatile gas analyzer was developed, which can be used for remote trace measurements of degassing from volcanic emissions (sulfur dioxide, carbon disulfide and chlorine and bromine oxides). The gas analyzer includes ultraviolet LEDs emitting in the near UV region of the spectrum, fiber bundle, a receiving-transmitting telescope, a spectrometer and a processing system. The article describes the method and some results of field measurements of sulfur dioxide and chlorine and bromine oxides.
