The present disclosure is directed to methods and systems for detecting a chemical substance. The methods and systems include chemically modifying a sample of a substance of interest through combination with a reagent to increase the volatility of the substance of interest. The systems and methods further include performing an analysis of the substance of interest.

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.

A method of measuring nitrate concentration in an aqueous sample include mixing the aqueous sample with a water-soluble thioether compound including a chromophore group in the presence of a water soluble catalyst; measuring a color change, and correlating the color change to nitrate concentration.

Multi-parameter water analysis system with a water parameter sensing device configured to wirelessly provide detector data and a smart phone displayable indicator of water analysis test results that are calculated by an analysis application that is updateable via a cloud-based data resource to account for a manufacturing change in indicator chemistry and/or an improvement in test result display. The water parameter sensing device includes an optical sensing apparatus configured to detect light from each of a plurality of indicators for different parameters when the indicator and a chemical parameter are exposed to each other, a processor to process information of the detected light, and wireless communication circuitry for communicating detector data based on the information about the detected light to a remote device. Social networking of water quality data allows sharing to other users.

A detection device for detecting analytes in liquid specimen is provided. The detection device comprises: a specimen chamber for collecting or storing a liquid specimen; a detecting chamber for containing a detecting element; and a through hole for transferring the liquid specimen between the specimen chamber and the detecting chamber. The through hole can be opened or self-sealed. The sealing or opening of the through hole controls whether or not the liquid specimen in the specimen chamber enters the detecting chamber via the through hole. Furthermore, a detection method is provided.

A panel for monitoring levels of biomarkers, including an assay having at least one inflammation monitoring test, at least one oxidative stress monitoring test, and at least one antioxidant activity monitoring test. A method of monitoring an individual's health, by collecting a sample from the individual, applying the sample to an assay panel, performing at least one inflammation monitoring test, at least one oxidative stress monitoring test, and at least one antioxidant activity monitoring test in the panel, and determining levels of biomarkers related to inflammation, oxidative stress, and antioxidant activity and therefore providing information regarding the individual's relative health and/or risk of developing one or more diseases.

Apparatus and methods are provided for analyzing a medical condition of a user. The apparatus may include a user interface configured to receive user identification information inputted by the user, an analyzer, and a processor all disposed within a common housing. The analyzer is configured to receive a biological specimen from the user and to analyze the biological specimen to generate analysis information. The processor is configured to store and forward the analysis information and to receive prescription information. The apparatus may include a communication unit configured to transmit the user identification information and the analysis information to a doctor at a remote location for review and to receive the prescription information from the doctor. The apparatus then may dispense the prescribed medication or print a medication prescription.
