The dynamic range of the measured benzene concentration is about 104.
One of the applications, in which the proposed analyzer can be used, is the determination of the benzene content in natural gas. Therefore, we tested the sensitivity of the analyzer using the same gas mixture generator as earlier for injecting benzene in the analytical cell, alternatively using methane, ethane, and propane, which are main constituents of natural gas, as the carrier gas instead of the air. It was ascertained that the sensitivity for these gases agrees with that for the air within the experimental error (5%).
