We introduce a compact mini-denuder air sampling device consisting of a regular gas chromatograph (GC) inlet liner for the simultaneous concentration of separate airborne gaseous and particulate phases in a single-step. Denuder materials are thermally desorbed in a regular inlet of a GC using routine equipment available in any chromatography laboratory. The simplicity of the technique makes it ideal for resource-poor laboratories.
