    摘要: Sampling of a broad range of chemicals using a handheld sampler body, having a sample screen in a sampling cassette; where a sample screen housing further consists of a locking arm arrestor body, where, the locking arm arrestor body including a draw tube, and where the sampling screen can be positioned in either a retracted or extended positioned regarding a sample access face. When activated, the system executes collecting and sampling operations of chemicals, by exposing the extended sampling screen to a sampling environment, drawing through the draw tube, air from the sampling environment, further collecting, onto the surface of the sample screen solid particles and/or pressing the sample screen against the surface(s) of object in the sampling environment. Then, removing the sampling screen from the sampling environment and isolating the plurality of airborne chemical contaminants, by retracting a sample screen into the sample screen housing.

    摘要: A method for detecting chemical aerosols and particulates on a surface by contacting a sample with a Surface Enhanced Raman Spectroscopy (SERS) substrate where the sample is an aerosol or a particulate on a surface, encapsulating the SERS substrate with the sample, heating the encapsulated sample so it vaporizes inside the encapsulation, cooling the vaporized sample so it deposits onto the SERS substrate, and irradiating the SERS substrate to collect a SERS spectrum of the sample. Also disclosed is the related system for detecting chemical aerosols and particulates on a surface.
