1. A portable spectrometer system, comprising:

  • a test strip having a fluorescent indicator and adapted to receive a sample to be analyzed, wherein the test strip comprises a substrate at least partially coated with a d10 metal salt; and

    further wherein the substrate is at least coated with a polymer selected from the group consisting of polyvinylpyrrolidone, polyvinyl alcohol, and combinations thereof;

    a fluorimeter comprising;

    a housing having a plurality of interconnected walls at least partially surrounding a cavity, at least one of the walls having an opening;

    a light source positioned in the cavity and adapted to emit light having a path;

    a support for receiving the test strip having the sample to be analyzed, the support located within the path of the light such that the light contacts the sample to cause an emission from the fluorescent indicator; and

    an optical spectrum separation assembly positioned to;

    receive the emission from the fluorescent indicator located at the support, separate the emission into an emission spectrum, and direct the separated emission spectrum through the opening;

    a mobile computing device comprising;

    an optical sensor positioned to receive the separated emission spectrum passing through the opening and to generate an image indicative of the separated emission spectrum; and

    a processor having instructions to analyze the image to determine the presence of and, if present, the identity of any illicit substance within the sample.
