Stability measurement

It is virtually impossible to assess a sample’s aging behavior from its condition at a single point in time.

That’s why Metrohm offers you stability measuring instruments that allow you to perform automated accelerated aging tests for natural oils and fats, fat-containing foods and cosmetics, biodiesel, and chlorine-containing polymers such as PVC. During these tests, the decay reactions that take place in the samples – i.e., their decomposition by oxidation or thermal degradation – are reproduced at elevated temperatures and thus drastically increased speeds.

The induction time, also known as oxidation stability index (OSI), is measured – or, in the case of polymers, the stability time. Below you can see Metrohm’s dedicated instruments for the above-mentioned sample types. All of these systems are compliant with national and international standards for stability measurement.
