항산화측정기 (Antioxidants and free radicals analysis system)
-First instrument available for the examination of the antioxidative capacity of both lipid soluble and water soluble substances on a single system.-Measurement of the total antioxidative capacity (sum parameters) of most diverse and complex substance mixtures.-Extremely short measuring times 3 min.-Very high sensitivity.-Needs only a few uL of the sample.-Dose not require any complicated or time consuming sample preparation.
PHOTOCHEM is using the method of photochemiluminescence. The method combines the very fast photochemical radical generation with the high sentivie luminometric detection. Free radicals (superoxide anion radicals) are produced by optical excitation of a photosensitizer. These radicals are partially eliminated from the sample by reaction with the antioxidant present in the sample. In the measuring cell the remaining radicals cause the detector substance to luminescence. Subsequently the anitoxidant capacity of the sample is determined in a separate cell by means of a photomultiplier tube(PMT). The results are presented in equivalent concentration units of ascorbate for water soluble substance or Trolox (synthetic vitamin E) units for liquid-soluble substances.
