Atomic Emission Spectroscopy, also known as AES Analysis and frequently known as AAS, is among the most useful analytical chemistry methods for direct component analysis of solid metal and metal samples. Laboratory Testing Inc. near Philadelphia, PA USA implements nuclear emission spectroscopy solutions for the identification and analysis of most common elements in the periodic table. Documented test results can provide qualitative and quantitative data. The spectrometers in LTI’s atomic emission Spectroscopy laboratory can analyse all common elements in metal and metal samples, such as soft metals like tin, zinc and lead. Information about major, minor and trace elements may also be offered. AES analysis is especially useful for Elements with a low atomic number like boron, aluminum, magnesium, calcium and phosphorous. Our newest Spectro Lab equipment has the capacity to examine Hafnium Hf, Tantalum Ta and Rhenium Re in Mar-M-247 alloys.
The test samples used in AES evaluation are Prepared by grinding the material to get a uniform, clean and flat surface. Find out the sample size necessary for testing and other guidelines for submitting samples. LTI’s atomic emission spectroscopy laboratory works with equipment with a spark source to make the energetic environment. The atoms in the sample are energized with a rapid series of high energy sparks in an argon-filled gap between an electrode cathode and the surface of the specimen. When the spark strikes the specimen, rapid heating of the sample happens and it vaporizes. The vaporization generates a spectrum of lines from every element that is present in the sample. These spectra are examined using a diffraction grating and a set of photomultiplier tubes to recognize the components and measure their concentrations.
According to the fundamental principle of atomic absorption spectroscopy Evaluation, when free atoms are placed into an energetic environment, they emit light at a set of wavelength bands, like the diffraction of light into a rainbow. These wavelength bands or emission lines form a pattern that is characteristic of the atom that generated it. Normally, the intensities of these lines are proportional to the number of atoms creating them. Element analysis by Atomic Emission Spectroscopy involves comparing the emission lines in the sample to known standards to identify the component and calculate the amount of the element. As a result, the elemental composition can be determined both qualitatively and quantitatively from the types and intensities of the emission lines.

LTI offers a number of analytical services That are employed for composition analysis to find out the types and amounts of components in a sample.
