Abstract
A method, an apparatus, and an integrated system using the apparatus for measuring a concentration of odorant in odorized gas which is produced by adding the odorant to un-odorized gas comprised mainly of hydrocarbon gas. In a detection absorbance measuring step, there is obtaining detection odorized gas absorbance which is absorbance of the odorized gas relative to a detecting ultraviolet light having high absorbability to the odorant and low absorbability to the un-odorized gas. In a subsequent concentration deriving step, the odorant concentration in the odorized gas is derived from the detection odorized gas absorbance.
