Elemental Analysis
In many applications e.g. the strength of steel or the light output of LED's, it is
important to use raw materials with the right composition. Variation in amounts of
O, N, H, C and S can have substantial influence on the properties of the product.
Using an elemental analyser these elements can be quantitatively determined in solid
materials and liquids.

Inductively Coupled Plasma- Mass Spectrometry (ICP-MS)
Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is a very sensitive analytical
technique with a high linear dynamic range (ultra-trace to main components). It is
capable of analysis of all elements from Li to U and can be applied to solutions,
solids and gasses. In ICP-MS sampled material is transferred by an argon flow to an
inductively coupled plasma in which an effective temperature of 8000 K results in
atomisation and ionisation of the material. Subsequently, the ions are extracted
into a mass spectrometer, with which the elemental composition of the material is
determined.

Nuclear Magnetic Resonance
(NMR)
NMR spectroscopy is a flexible non-destructive analytical technique that
gives access to numerous chemical and physical properties of materials.
Sampled material is placed in a magnetic field and subjected to a broad
spectrum of radio frequency waves (10 – 900 MHz). From this spectrum
narrow lines are absorbed by atomic nuclei. These absorption bands are
recorded as signals in the NMR spectrum.
A well-known application of NMR is Magnetic Resonance Imaging (MRI),
which is used for medical diagnostics.Typical applications in material sciences
are quantitation and molecular characterization of main chemical
components and/or contaminants. More sophisticated applications are
complete molecular structure elucidation, assessment of (polymerization)
reaction kinetics, and determination of diffusion constants. Download here....
Raman Spectroscopy
Material analysis in complete devices can be difficult to perform, as direct
contact with the material of interest may not be possible. In such a situation,
Raman spectroscopy is a realistic option. This technique is based on
the fact that energy lost during the scattering of laser light contains chemical
information about the irradiated material. Because water and glass
result in little inelastic scatter, analysis can be performed in aqueous solutions
or through glass windows. The latter characteristic makes the technique
very suitable for on-line, non-destructive analysis. Download here....
Scanning Probe Microscopy
(SPM)
Scanning probe microscopy (SPM) provides information on the nanometer
scale. Using a very sharp tip, height profiles can be measured with
a resolution better than 1 nm. Measurements can be performed in an
inert atmosphere, at elevated temperatures and even in liquids such as
water. Beyond height information, SPM offers the possibility to study
mechanical properties as well as electrical and magnetic behaviour of
materials. Attaching functional groups to the sharp tip even allows
imaging of chemical and biological interactions on a nanometer scale. Download here....
X-ray Diffraction (XRD)
X-rays are electromagnetic waves with a wavelength in the range of interatomic
distances (0.1-10 Å).This match of length scales makes them suitable
for the study of crystalline materials. For single-phase materials the
crystal structure can be obtained directly using X-Ray diffraction (XRD).
With the help of a database of known structures XRD can be used for
phase identification. Also crystal size, strain and preferred orientation of
polycrystalline materials can be measured.The related technique of X-ray
reflection enables accurate determination of film thickness. Download here....

A Focused Ion Beam (FIB) makes use of Ga-ions to remove material with
a very high spatial precision. In this way cross-sections can be made on a
specific location. The resulting samples can either be studied directly in

analysis. When both Ga-ions and certain gases are applied, it is also
possible to deposit material. Therefore, the FIB can be used as a
multifunctional tool in a broad range of applications. Download here....
Rutherford Backscattering
RBS is a well-established technique in thin film characterisation in which a
beam of high energy (2 MeV) helium ions is directed at a sample.The helium
ions elastically scattered by nuclei in the sample are detected. The
higher the mass of an atom that is hit by a helium ion, the higher the energy
of the ion will be after backscattering (comparable to collisions between
billiard balls). This results in mass discrimination. By counting the helium
ions as a function of energy, the number of atoms of each element present
can be determined. Download here....
