Material analysis - OES - Ingenieurbüro Kukuk

Authentication by means of spectrometry

Spectrometry (optical emission spectrometry, OEM) is used to determine the material composition, i.e. the elements that make up the material in percent. Subsequently, the age of the material can be determined on the basis of the elements and the manufacturing process, at best with an accuracy of up to a decade.

We only use accredited methods: Spectral analysis, spark OES for sophisticated material analysis. We maintain a variety of analytical methods to optimally meet your requirements. Mobile use and on site at your vehicle we determine the chemical composition of the materials with high precision and can then carry out an originality analysis and dating with our sworn material analysts. No material has to be removed, no sample has to be taken and no other destructive measures have to be taken.

Spectrometry, as a forensic / scientific method of testing the authenticity of a vehicle, is used in our engineering office. since 1986 applied. For 9 years now, we have been able to carry out the determination of the material composition, in the required quality / thousandths range, almost non-destructively and mobile. This means that we can carry out a corresponding investigation at any time, both nationally and internationally. To date, we have been able to expand our experience on the west and east coasts of North America, South America, Tokyo, Moscow, northern Italy, England, Belgium, the Netherlands, Switzerland and in Austria.

Analysis of metals and alloys on the spark spectrometer

With this method, all common metallic materials can be analysed:

Cast iron
unalloyed steels
Low alloy steels
Low-alloy and high-alloy stainless steels
Aluminium materials and aluminium alloys
Copper materials and copper alloys
Nickel-based alloys
Titanium materials

Our high-precision mobile spark emission spectrometer from Spectro is used for the precise qualitative and quantitative determination of chemical elements in metals, using the optical emission spectrum of atoms or atomic ions. It determines all elements used in the metal industry, including trace analysis of carbon, phosphorus, sulphur and nitrogen.

Radio spectrometer OES

A spark spectrometer (spark emission spectrometer) is a device for the qualitative and quantitative determination of chemical elements in metals and uses the optical emission spectrum of atoms or atomic ions for this purpose (hence also spark optical emission spectrometer or spark OES). For the analyses, a spark or electric arc is used between an electrode and a prepared material sample. This vaporises sample material and excites the released atoms and ions by electron impact. The emitted radiation is optically split into its individual spectral components. Each element contained in the sample emits radiation at several wavelengths, which can be detected by semiconductor sensors or photoelectron multipliers. The radiation intensity measured in this way is basically proportional to the amount of the corresponding element and thus enables the determination of its content or concentration in the sample material.
