Abstract
A method and system for the suppression and/or modulation of absorption spectrum artifacts for the purpose of gas detection and concentration measurements using at least one magnetic, electric or electromagnetic field. A field applied selectively to at least one section of the system modulates absorption by influencing quantum energy state transitions of gas species.
