Abstract
A system for the measurement of free and bound SO2 in a liquid beverage product sample comprising a sample container having a volume sufficient to provide a headspace above the sample into which a gas can pass; a gas flow system adapted to extract gas from the headspace and recirculating it back into the liquid volume; a measurement system configured to monitor a time dependent evolution of SO2 in gas from the gas flow system; and a dosing apparatus fluidly connected to the container to supply an hydrolysis reagent thereto. A heater unit is provided for supplying thermal radiation into the container to elevate the temperature of sample therein sufficient to facilitate the hydrolysis reaction and a signal processor operates to deconvolute the monitored evolution to generate an indication of the concentration of each of the free SO2 and the total SO2 content of the sample.
