Claim 17:
18. A method of analyzing a chemical composition comprising:
providing a mobile chemical sensor device and a chemical sensor probe, wherein the chemical sensor probe includes an array of luminescent chemical sensors on a sensor-bearing surface;
contacting the chemical sensor probe with a chemical composition for a test duration;
inserting a cartridge holding the chemical sensor probe into the mobile chemical sensor device;
exposing the chemical sensor probe to a test range of light; and
detecting a color and an intensity of luminescence of the array of luminescent chemical sensors,
wherein the mobile chemical sensor device includes, a housing including a cartridge opening configured to position the cartridge holding the chemical sensor probe, wherein the cartridge forms a light sealed enclosure in an interior of the housing when the cartridge is inserted in the cartridge opening;
at least one light source configured to direct light onto the sensor-bearing surface of the chemical sensor probe at an angle of incidence, wherein the light source is capable of emitting light having a wavelength of from about 280 nm to about 400 nm; and
a camera module mounted in the light sealed enclosure and configured to detect emitted light from the chemical sensor probe,
identifying an identification code of the chemical sensor probe by scanning an optical tag or a radio frequency tag mounted on the chemical sensor probe;
matching the identification code to an eligible identification code in a database;
measuring emitted light from the array of luminescent chemical sensors in a baseline reading step, providing baseline data from the chemical sensor probe and forming a pre-scanned chemical sensor probe;
identifying the identification code of the pre-scanned chemical sensor probe by scanning the optical tag or the radio frequency tag mounted on the pre-scanned chemical sensor probe;
matching the identification code to an eligible identification code of a pre-scanned chemical sensor probe in the database; and
measuring emitted light from the array of luminescent chemical sensors in a test reading step, providing test data from the pre-scanned chemical sensor probe.
