An apparatus for capturing a target analyte in advance of performing spectroscopic analysis to determine the existence of the target analyte from a source contacted with a collection substrate. The collection substrate is fabricated of a material selected to have an affinity for the target analyte, sufficiently transparent in a spectral region of interest and capable of immobilizing the target analyte thereon in a manner that limits scattering sufficient to obscure spectral analysis. The collection substrate may be coated with a material selected to react with, bind to, or absorb the target analyte. The target analyte may be captured to the collection substrate by one or more of wiping, dabbing or swabbing a target analyte carrier with the collection substrate.

Apparatus for preconcentrating and transferring analytes from surfaces and measurement thereof using spectroscopy

A system and method for capturing a target analyte in advance of performing spectroscopic analysis to determine the existence of the target analyte from a source contacted with a collection substrate. The collection substrate is fabricated of a material selected to have an affinity for the target analyte, sufficiently transparent in a spectral region of interest and capable of immobilizing the target analyte thereon in a manner that limits scattering sufficient to obscure spectral analysis. The collection substrate may be coated with a material selected to react with, bind to, or absorb the target analyte. The method optionally includes the step of transferring the captured target analyte to a second substrate, which may be an optical substrate. The target analyte may be captured to the collection substrate by one or more of wiping, dabbing or swabbing a target analyte carrier with the collection substrate.
