MechTest is one of a small number of laboratories that have gained NATA accreditation
for OES, which stands for Optical Emission Spectroscopy
Optical Emission Spectroscopy relies on the principle that when a sample is subjected
to a high-energy heat source (typically a plasma or an electric arc), it emits
light at specific wavelengths that correspond to the elements present in the
sample. This emitted light is then analysed to identify and quantify the elements.
The sample is introduced into the high-energy heat source, causing it to vaporize
and form a high-temperature plasma. As the sample atoms or ions return to
lower energy states, they emit light at characteristic wavelengths. The emitted
light is passed through a spectrometer, which disperses the light into its individual
wavelengths. The intensity of the emitted wavelengths is measured by a detector.
A computer analyses the emitted wavelengths and their intensities to identify the
elements present and determine their concentrations.
Quantification: Quantification is typically achieved by comparing the intensity of
the emitted lines to known standards or calibration curves. This allows for the
determination of the concentration of each element in the sample. OES is widely
used in various industries, including metallurgy, environmental monitoring, quality
control in manufacturing, and research. It is especially valuable for detecting
trace elements and contaminants in materials and environmental samples.
Chemical Analysis of Carbon steel
Aluminium and its alloys
Copper and its alloys
Ametek SpectroMAXx M
MechTest has a SpectroMaxX M OES chemical analysis instrument .We are one of a few laboratories with NATA accreditation for this procedure. We test and analyze Carbon Steels, Stainless Steels and other Alloys. The instrument can provide chemical analysis of a range of elements including: iron, aluminium, carbon, boron, silicon, sulfur, manganese, nickel, chromium, copper, etc.
The spectrometer sparks an item via a high voltage discharge which vaporises a small amount of the metal. This allows spectrum analysis of the vaporised discharge to determine chemical composition. Results from the analysis can then be used to determine conformance with a specified published standard, or entered into a metals database to determine the nearest matching grade.
