Abstract: A detection system for testing a targeted substance includes: a pad that includes a test area for receiving the targeted substance; and an image readable by an image sensor and positioned a predetermined distance from the test area, the image being configured to facilitate alignment of the image sensor with the testing area for a colorimetric analysis based on the predetermined distance between the image and the test area.

Abstract: A detection system method of color balancing an image includes receiving an image of a test area of a pad which includes a color of a reaction between a test substance and at least one reagent on the test area of the pad, an alignment code having detection system identification information, at least one color calibration block indicia for aligning with a camera as the image is being captured, and test identification information for analyzing the test substance during a colorimetric analysis. The method further includes collecting an array of pixels of RGB values for each pixel in the image, evaluating a captured color of the at least one color calibration block in the image, and performing the colorimetric analysis on the reaction between the test substance and the at least one reagent.

Abstract: In some embodiments, the present disclosure pertains to substance detecting assemblies that include: (1) a sample medium (e.g., filter paper); and (2) a solid test chemical (e.g., zinc) impregnated with the sample medium. In some embodiments, the present disclosure pertains to methods of making an assembly for detecting a substance by: (1) providing a sample medium; (2) providing a solid test chemical; and (3) impregnating the sample medium with the solid test chemical. In further embodiments, the present disclosure pertains to methods for detecting a substance by: (1) collecting the substance on a sample medium that is impregnated with a solid test chemical; and (2) initiating a reaction of the substance with the solid test chemical on the sample medium to generate a color that corresponds to the substance. In some embodiments, the sample medium is then inserted into a chemical detection unit for the detection of the substance.

Abstract: Embodiments of the present disclosure pertain to a colorimetric system for detecting a substance, the colorimetric system that includes a first chemical container adapted for releasing a first chemical; a second chemical container adapted for releasing a second chemical; a flow modulation sheet adjacent each chemical container; and an encapsulation covering the flow modulation sheet and each chemical container, where the encapsulation comprises a window defining a target area of the filter paper such that the target area is adapted for applying the substance; where the flow modulation sheet comprises a design adapted for automatically controlling a first flow of the first chemical and a second flow of the second chemical to the target area after simultaneously releasing the first and second chemicals; and where the design comprises a first void disposed in the flow modulation sheet.
