PetroOXY - Method
5 ml of a sample is heated together with oxygen in a small hermetically sealed test chamber. This initiates a very fast artificial aging process, that is displayed by a pressure drop in the system.
It was found that the time consumption to the pressure drop is directly related to the oxidation stability.
The results include all volatile & non-volatile oxidation products, thereby provide a complete analysis of the sample's oxidation stability.

Economical Aspects and Advantages
The oils and fats contained in food are also subject to oxidation, which leads to their spoilage. As well as for determining the oxidation stability of foods, the PetroOxy can also be used for testing cosmetics or cosmetic additives.
The PetroOXY-Method performs a massive reduction of testing time. The handling & cleaning time per test is limited to approx. 5 min.
As a result of improved repeatability, for producers there is the possibility of cost saving, because now the concentration of valuable additives can closer be limited to the required level.

The Automatic Rapid Small Scale Oxidation Tester (RSSOT) PetroOXY
complies with requirements of users regarding an improvement of the currently used Oxidation Stability Tests.

• small sample volume of 5 ml
• short test time, normally less than 1 hour
• improved user safety
• automatic pressure detection system
• automated oxygen charging & relief
• automatic heating & re-cooling
• easy handling even for less qualified users
• no complicated evaluation (soon as the test is finished the result is displayed)
• interface to transfer test data
• easy cleaning after test run

To boost the re-cooling of the chamber between two tests a Metal Re-Cooling Block is available. It must be stored in a separate freezer. Especially useful in an warm environment.

High-graded Stainless Steel Chamber in dairy-product quality.
Suitable for: water containing products and acid forming samples in the food & cosmetic sector.
