Abstract
In the invention, a collection device includes a flow through micro scale plate arranged to collect analyte. The plate includes holes, and sorbent coating on contact surfaces of the plate. The holes pass analyte fluid flow, for example analyte vapor so that fluid flow for collection may be generally perpendicular to the sorbent plate. Preferred embodiment plates include an integrated heater trace. In preferred embodiments, a high substantially perpendicular flow is used for collection and concentration, and during desorption and delivery a low substantially parallel flow is used. The low flow is selected to meet constraints of a detector system.
