FLAT ROOFING
AND
ETICS SYSTEMS
The principal scientific basis of our techniques is Atomic Emission
Spectroscopy (AES) and involves energising the atoms of a sample and using
light spectra to determine the elemental composition. In our case we use
visible, ultraviolet and infrared light. X-Ray spectra is handled differently.
The absorption and emissions are referred to as atomic spectral lines and are
created by the electronic transitions of outer shell electrons as they rise and
fall from one electron orbit to another. Separately, atoms have distinct X-Ray
spectra that are attributed to the excitation of inner shell electrons moving to
excited states (this is the principal used in XRF spectroscopy).
The services offered by Evolution Fasteners (UK) Ltd are the elemental
analysis/ composition quantification and/ or positive material identification of:

We utilise the cutting edge in Optical Emission Spectroscopy (OES), X-Ray
Fluorescence Spectroscopy (XRF), Ultra-Violet Spectroscopy (UV-Vis) and
Fourier Transform Infrared Spectroscopy (FTIR) to provide accurate elemental
quantification and Positive Material Identification (PMI).
The different implementations of this
through OES (Optical Emission), XRF
(X-Ray Fluorescence), FTIR (Fourier
Transform Infrared) and UV-Vis
(Ultraviolet/ Visible light) can excite
observe and record certain elements,
which is why Evolution utilise the full
suite of techniques to account for
almost all elements in the periodic tables
of elements.

Evolution Fasteners (UK) Ltd utilize the most modern and advanced
spectroscopy techniques available at the cutting edge of science to determine
the elemental composition of various metallic alloys, powders, liquids and
polymers used in construction products as well as being applicable in other
sectors such as Defence, Automotive, Aerospace and Pharmaceuticals.

INFORMATION
SPECTROMETRY
Atoms of different elements have
distinct and unique spectra: this
allows the identification and quantification of a sample’s elemental
composition.
As an example; the unique spectra
of Hydrogen, Neon and Iron can be
seen here in the form of Fraunhofer
lines (emission).
