Abstract
The invention disclosed herein relates to a dry sensor for measuring the concentration of an analyte in a liquid beverage sample. Described herein is a novel dry sensor which is able to receive a liquid sample and adjust the pH of the liquid to be suitable for assaying an analyte of interest without the need to add reagents to the sample and/or to perform manually timed operations and able to detect a redox reaction in the presence of a liquid sample. The meter disclosed herein, when connected to the sensor disclosed herein is able to adjust the temperature of the liquid to be suitable for the assay, apply a series of potentials, measure the current at several times, measure the diffusion coefficient of the limiting electrochemical species, calculate the concentration of one or more analytes, and rapidly provide the user with the required information on the liquid sample.
