Stability Measuring Instruments

Accelerated determination of stability at elevated temperature

Metrohm Stability Measuring Instruments are the ideal equipment for the following applications:

  • Oxidative stability of edible fats and oils
    (see: Application Notes R-1 to R-7)
  • Development of antioxidants for food industry
  • Oxidative stability of fat containing products: cereals, biscuits, cookies, hazelnuts
  • Oxidative stability of FAME (fatty acid methyl ester, biodiesel)
    (see: Application Note R-9)
  • Determination thermal stability of PVC and PVC related polymers (see: Application Note R-8)
  • Examination of PVC additives auch as stabilizers or plastilizers
    (see: Application Note R-8)
  • More applications

Instruments

Our Stability Measuring Instruments are now available in the third generation and are well approved in food industry and polymer industry. They are completely PC controlled and offer extensive features for data archiving and data reprocessing.

Methodology

With Metrohm Stability Measuring Instruments different types of samples are exposed to air or inert gas at elevated temperatures. Due to oxidative or thermal decomposition volatile reaction products are formed during this reaction process and are trapped in an absorption vessel with distilled water and are detected using conductivity measurement.
