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 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.

Compared to some other oxidation and storage stability test methods, this test method uses a small sample and gives a result in a short time period.

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

The Active Re-Cooling Device uses Peltier cooling. It allows an automatic re-cooling to a defined temperature in the range of +17 to +24 °C. Fully self-contained and liquid-free it is a very easy and safe way of testing. Especially recommended for easy vaporizing fluids like gasoline.

The high-graded Aluminum Chamber with galvanic coating is used to provide an even and super fast heat transfer. The coating of the cell avoids catalytic effects.
Suitable for: fuel, oil and with a sample dish for grease but not for water containing products.
