Abstract

The present gas analyzer allows for the effective measurement of the concentration of one or more gases or vapors within a sample. The gas analyzer utilizes a plurality of reference filters that are located between the source and the sample region to enhance the measurements associated with the sample filters. The gas analyzer also utilizes a gas channel to facilitate the circulation of scrubbed gas between two separate housing sections.
