Rapid Testing
Portable FTIR Oil Analysis in Seconds
E
ralytics ERASPEC OIL is the first
portable, stand-alone FTIR oil analyser on the market. It is the ideal solution
for onsite measurements, as it provides
immediate feedback about the status of
the oil. It is also optimal for use in remote
areas. With its compact (weighing just
8kg) and full metal housing, this analyser
brings lab quality results to the field. Its
built-in PC and the colour touchscreen
allow the direct display of the oil spectra
as a graphic chart. As several thousands
of spectra can be saved in the instrument
memory, the samples can be analysed and
immediately compared with other spectra.
Lubrication is a vital component
of machinery. Early detection of lube
oil degradation and engine wear is
essential for avoiding unnecessary
maintenance, while reducing the risk
of breakdowns. Infrared (IR) analysis is an inexpensive test that
can provide information about
the chemical condition of the
lubricating oil and also provide
inferences about the state of
the machine component. IR
analysis has become a routine
method of oil analysis because
of its speed, reliability of
results and the large amount of information it generates from the IR spectrum.
With its patented FTIR spectrometer
ERASPEC OIL offers highly reliable
lubricant oil condition monitoring in full
compliance with the latest ASTM, DIN
and JOAP methods. ⚛

The Solution to Investigating Oxidation Stability
W
hen in contact with atmospheric
oxygen, the chemical decomposition of samples containing natural
fats or other lipids begins. Oxidation
stability characterises the resistance of
the sample to oxidation. It is a necessary
requirement for shelf-life investigations,
quality control and product development.
Anton Paar’s RapidOxy oxidation
stability tester accelerates the oxidation
process by increased temperature and
oxygen pressure. RapidOxy represents
an alternative test method to determine
the oxidation stability of cosmetics,
vegetable and animal oils and fats in a
minimal test time.
It is based on their patented measuring principle of ASTM D7545,
which is an accepted method to test the
oxidation stability of diesel, biodiesel
and blends.
RapidOxy works directly on the
whole sample, making preliminary
sample preparation unnecessary. It
requires only small sample volumes
(5ml - 10ml). Solid samples and semisolid samples are just put into a PTFE
dish and placed inside the stainless
steel test cell with excellent chemical
resistance.
The sample is pressurised with pure
oxygen and heated, which initiates
a very fast oxidation process that is
displayed at the end by a typical pressure drop of 10% or defined by the user
application.
The RapidOxy also comes with a
safety and isolation hood. The instrument is approved by the Federal Institute for Materials (Germany). ⚛
