Laboratory Techniques:
ICP Inductively Coupled Plasma
Spectroscopy:
Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP)
is a multi-element analysis technique that dissociates a sample
into its constituent atoms and ions.
A wide range samples can be analysed by ICP. Sample types
include petroleum based products, gases, catalysts, deposits,
polymers, fine chemicals, additives, food products, cosmetics,
pharmaceutical products, steels, alloys, soil, water, paints
and dyes.
The Sunbury lab uses a variety of solublisation techniques
including high-pressure microwave digestion and digestion/fusion
methodology. The ICP facility is backed by AA, XRF and classical
wet chemistry techniques.

GC
Gas Chromatography:
Sunbury is equipped to carry out IP, ASTM, DIN and other methods
on dedicated GC instrumentation.
GC analyses include PIONA oxygenated gasolines; simulated
distillation on crude oils, products and sulphur speciation
on gasolines and diesels.
GC detectors include flame ionisation, thermal conductivity,
electron capture, sulphur, nitrogen and GC/MS. The lab analyses
refinery streams, refinery products, sludges, contaminated
gas, liquids and solids, effluents, exhaust gases and other
refinery and petrochemical plant products and waste streams.
FTIR Fourier Transform IR Spectroscopy:
FTIR spectroscopy is quick, non-destructive and relatively
inexpensive technique and is used for quality control, used
oil analysis, component identification and quantification
of additives.
The IR spectrum offers physical "non-destructive" methods of sample measurement. FTIR information reflects chemical
and physical characteristics ofa sample.
Most petroleum products are mixtures and the IR spectrum is
an additive function of the components, however the spectrum
is still characteristic of that product.
Separation techniques are used to isolate and concentrate
components before acquiring spectra.
AAS Atomic Absorption:
Intertek Sunbury Technology Centre offers Flame Atomic Absorption Spectroscopy (AAS), graphite furnace AAS (GFAAS) and dedicated cold vapour AAS for specialised mercury analysis. Using a variety of dissolution techniques including high-pressure microwave digestion and traditional fusion methodology, a wide range of sample types may be analysed. |
