A Hyphenated Preconcentrator-Infrared-Hollow-Waveguide Sensor System for N2O Sensing.

ABSTRACT: Following the Kyoto protocol, all signatory countries must provide an annual inventory of greenhouse-gas emission including N2O. This fact associated with the wide variety of sources for N2O emissions requires appropriate sensor technologies facilitating in-situ monitoring, compact dimensions, ease of operation, and sufficient sensitivity for addressing such emission scenarios. In this contribution, we therefore describe an innovative portable mid-infrared chemical sensor system for quantifying gaseous N2O via coupling a substrate-integrated hollow waveguide (iHWG) simultaneously serving as highly miniaturized mid-infrared photon conduit and gas cell to a custom-made preconcentrator. N2O was collected onto a solid sorbent material packed into the preconcentrator unit, and then released via
