摘要：
An integrated condenser is described. This integrated condenser includes an outer surface region on a sampler surface that facilitates condensing at least a component in a received gas-phase sample into liquid-phase droplets on the sampler surface, and aggregating and moving the condensed droplets radially toward an inner surface region on the sampler surface that receives the condensed droplets. For example, the outer surface region may include a set of micro-patterned concentric rings, each of which includes a set of radially oriented wall-groove pairs. Moreover, the sampler surface may be increasingly less hydrophobic along a radial direction toward the center of the sampler surface, thereby creating an axisymmetric wettability gradient.
