ATOMIC EMISSION SPECTROSCOPY

AES ANALYSIS IN METAL SAMPLES

Atomic Emission Spectroscopy (AES), sometimes called Optical Emission Spectroscopy (OES), is a highly valuable method for directly analyzing the elements present in solid metals and alloys. At CCT in China, we offer AES services for the identification and analysis of all major elements on the periodic table. Our documented test results provide both qualitative and quantitative data to our clients.

RANGE OF ANALYSIS

CCT's atomic emission spectroscopy laboratory is equipped with spectrometers capable of analyzing all the common elements present in metal and alloy samples, including major, minor, and trace elements. Our lab can provide analysis for a variety of materials, such as iron and steel, superalloys, cast iron, aluminum alloys, copper alloys, and more.

To prepare test samples for AES analysis, the material needs to be ground to obtain a uniform, clean, and flat surface for testing. The sample size required for testing may vary depending on the instrument used and the type of sample being analyzed. It is recommended to consult with the laboratory beforehand to determine the appropriate sample size and preparation method. Additionally, it is important to follow the guidelines provided by the laboratory for submitting samples, which may include labeling, packaging, and shipping instructions to ensure the safe and accurate analysis of the samples.

THE ATOMIC EMISSION SPECTROSCOPY TEST PROCESS

CCT’s atomic emission spectroscopy lab uses a spark source to create an energetic environment for elemental analysis. This involves applying a rapid series of high-energy sparks to the surface of the sample in an argon-filled gap between an electrode (cathode) and the sample. This results in rapid heating and vaporization of the sample, producing a spectrum of emission lines from each element present in the sample. These lines are analyzed using a diffraction grating and photomultiplier tubes to identify the elements and determine their concentrations.

The basic principle of AES analysis is that when free atoms are energized, they emit light in a series of wavelength bands, much like the diffraction of light into a rainbow. The emission lines form a pattern that is unique to each atom, and the intensities of the lines are proportional to the number of atoms producing them.

Using AES analysis, elemental composition can be determined both qualitatively and quantitatively by comparing the emission lines from the sample to known standards. This allows for the identification of the element and calculation of its quantity in the sample. The spectrometers in CCT’s atomic emission spectroscopy lab can analyze all common elements in metal and alloy samples, providing information on major, minor, and trace elements. Our laboratory is capable of analyzing a variety of materials, including iron and steel, superalloys, cast iron, aluminum alloys, and copper alloys.
