Analyser for measuring antioxidant levels in foods
Measuring antioxidant levels plays an important role in a host of applications including characterisation of food quality, control of food processing technologies, improvement of product shelf life, measurement of the antioxidative efficiency of food additives, authenticity control and development of novel formulae. Antioxidants are an essential part of the bodys defence mechanism against cell damage by free radicals. The Photochem analyser provides a rapid and accurate way of measuring water-soluble and lipidsoluble antioxidants in a single system. The instrument uses the principle of photochemiluminescence, combining very fast photochemical radical generation with highly sensitive luminometric detection. Extremely easy to use, each measurement takes less than three minutes. There is no complex or time-consuming sample preparation and only a few microlitres of sample are needed. Sampling, measurement and rinse cycles are performed completely automatically. The anti-oxidative capacity of the sample is measured by comparison with a calibration curve.
