A review of sampling and pretreatment techniques for the collection of airborne amines

Abstract

This review critically assesses the methodologies available for sampling and pretreatment of amines in air and bound in airborne particulate matter. We emphasize the most common techniques reported to date for the collection of vapor-phase amines based on sorptive media [solution (e.g., with the aid of impinger), solid sorbents, solid-phase extraction (SPE), solid-phase microextraction (SPME), and denuder] or other approaches (e.g., derivatization). Moreover, we extend discussion to cover amines found in airborne particulate matter through membrane filters, impactors, or scrubbers. Finally, based on measurements made under laboratory and field conditions, we discuss the advantages and the disadvantages of each sampling and pretreatment technique for key amine species.
