Abstract Information :
Thermal desorbers were originally developed in response to a need to detect relatively low-boiling volatile organic compounds (VOCs) in ambient air. However, new developments have allowed this capability to be extended, with modern TD instruments being capable of monitoring compounds boiling up to C44.
Does this universality of TD also apply to the sampling technique - specifically is there a single sampling technique that can give the best method detection limits and response RSDs? The answer is no, and this poster will describe the factors that need to be considered in coming to a decision about the best sampling method (and sampling parameters) for TD-based quantification of organic vapours ranging from C2 to C44.
