A method for analysis of freshness of fuels, food products, and oils, lubricants and other fluids, and other organic materials, is disclosed which quickly analyzes oxidative degradation of a sample off-line by measuring the oxidation products of the material. A sample of the material is dissolved and subjected to single sweep voltammetric analysis to measure the current through the sample as a function of the potential applied. The resulting current-voltage plot reflects the level of oxidation products present in the material sampled. The method results in data which can be used to evaluate the freshness of unused materials which degrade during storage, as well as to monitor deterioration of materials during use.
