Abstract
A method of analyzing a selected refinery chemical at a low concentration comprises contacting a sample with functionalized metallic nanoparticles that contain metallic nanoparticles functionalized with a functional group comprising a cyano group, a thiol group, a carboxyl group, an amino group, a boronic acid group, an aza group, an ether group, a hydroxyl group, or a combination comprising at least one of the foregoing; radiating the sample contacted with the functionalized metallic nanoparticles with electromagnetic radiation at a selected energy level; measuring a Raman spectrum emitted from the sample; and determining the presence or a concentration of a selected refinery chemical in the sample from the Raman spectrum.
