A system is provided for performing metal trace analysis on a liquid sample. A sample holder holds an analysis substrate that includes a reference region and at least one test region. An ultraviolet (UV) light source emits ultraviolet light illuminating the liquid sample. An optical sensor detects radiation emanating from the liquid sample and converting the detected radiation into an electrical signal. A microcontroller processes the electrical signal. An external interface transmits the processed electrical signal to an external device. The analysis substrate is configured for manual movement by a user. A tracking system detects a sample scanning location for the metal trace analysis, and includes a light source, other than the UV light source, and another optical sensor. The other optical sensor detects light emitted by the light source.

A characteristic of edible oil may be evaluated using a spectrometer. For example, optical reflectance data may be obtained from edible oil in situ in a frying apparatus housing the edible oil, the reflectance data corresponding to a specified range of infra-red wavelengths. A model profile corresponding to the characteristic being assessed may be obtained, such as from a repository housing a secured library of such profiles. The model profile may define a regression vector for use in transforming the reflectance data to generate a value corresponding to the characteristic being assessed. A criterion may be applied to the value to establish a simplified representation of the characteristic for presentation to a user for assessment of oil quality.

The present disclosure relates to a system and method for automatic online monitoring of dimethyl sulfide in environment. The method may realize separation of water vapor and the substance to be detected in accordance with the adsorption phase equilibrium principle of substance, thus eliminating the influence of water vapor on detection. The disturbance of other substances in an environmental sample can be eliminated in accordance with the charge or proton transfer principle of molecule ion reaction. Automatic online sampling, preprocessing and sample injection units are configured using valves, numerically controlled motor-driven injectors, flow controllers and a peristaltic pump, so that continuous online detection of DMS in an environmental water sample (e.g., seawater, or lake water) or a gas sample (e.g., atmosphere) can be realized.
