Oxidation Stability (RSSOT) -
PetroOXY "Block-Cooling"
ASTM D 7525 (Gasoline), EN 16091 & ASTM
D 7545 (Diesel, Biodiesel (FAME) & Blends)
Detail
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 Metal Re-Cooling Block must be stored in a separate
freezer to boost the re-cooling of the chamber between two
tests.
Especially useful in an warm environment.
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.
