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.

摘要： A method and apparatus for measuring dissolved residue concentrations and particulate residue particle concentrations and size distribution in liquids, particularly colloidal suspensions. The method involves separating dissolved and particulate residues in liquids for subsequent analysis of the residue species. The method includes the steps of forming an aerosol from the liquid sample to be analyzed, evaporating the droplets in the aerosol to dryness, detecting and sizing the particles, and determining the liquid volumetric inspection rate. An apparatus for separating dissolved and particulate residues in liquids for determination of the concentrations of the two residue species as well as the size distribution of the particulate species is also disclosed. The apparatus includes a droplet former, a dryer communicatively connected to the droplet former, and a detector communicatively connected to the evaporator for detecting and sizing particles.
