Problems solved by technology

As far as interpretation is concerned, the numerical scale cannot be obtained with these devices, and it is left to the observer to judge the color spectrum to determine, and its resolution and accuracy are questionable
[0007] However, there are currently no inventions claiming the use of measuring devices involving the active diffusion of target molecules in chemical reactions leading to changes in quality or markers associated with changes in the integrity of the environment through engineered structures using extraction, Orientation of the engineered structure such that the moving front is synchronized with mass changes in the environment under study

Embodiment Construction

[0053] Two types of measurements are possible in the present invention: current level and cumulative exposure. The former measures analyte levels recorded at the time of measurement, while the latter measures cumulative exposure units and reports exposure history. In both contact cases, metering and reporting can be done as a continuous scale with strips moved by the reaction front or as a discrete scale and a graduated scale. Readouts can be visual or electronic. Observations can be made as visual readings for non-technical personnel, or as electronic readings relayed by radio waves or by other electromagnetic means for technicians skilled in the use of the device and reported to a remote centre.

[0054] Food and biological agents lose quality during distribution when they are exposed to heat for a period of time and when they become contaminated with spoilage organisms. Quality loss and residual quality can be measured by bacterial and fungal metabolites from food spoilag...

Abstract

The invention provides a method for quantitatively sensing, using an indicator system based on diffusion in space and time of a reaction front, for determining and reporting the prevailing concentration or exposure history of an analyte in food, beverage, and pharmaceutical monitoring for the state of quality, for ripeness indication in fruit, for monitoring environments for concentrations of sanitisers, pollutants and nutrients, for monitoring the residual life of filters, and for monitoring stream flows.

Description

technical field [0001] The present invention generally relates to devices and methods for sensing changes in concentration or exposure history of analytes involved in the fields of food and beverage quality, drug spoilage, personal protection, and environmental integrity Chemical reactions affecting quality control. Background technique [0002] There are several gas detection technologies that have been integrated into electronic devices, often utilizing colored indicators combined with luminescent, fluorescent, reflective technologies. These devices require manual operation, calibration and interpretation by a skilled technician. Examples of patents containing these devices include GB2102947, US5094955, WO0077242, W09627796, US6908746 which can be used to detect spoilage products from bacteria in food and blood, and US2890177, US3068073, US3111610, US3754867 which can be described as gas detectors. [0003] Visual readings are used in the Draeger Values ​​are read in f...
