Atomic absorption spectroscopy (AAS) is process used by AEIS to accurately quantify Ca, Cu, Cd, Al, Fe, Zn, Pb in materials.
Atomic absorption spectroscopy can be used to analyze the concentration of over 62 different metals in a solution .The concentrations of metals in the samples are also measured by it in the low range of mg/L. Atomic Absorption Spectroscopy is a technique which measures the radiation absorbed by chemically unbound atoms. This is achieved by analyzing the transmitted energy relative to the incident energy at each frequency. Atomic Absorption Spectroscopy could be used for different kind of analysis such as: Pharmaceutical, Environmental, Clinical, Mining Industry, etc.
AEIS follows and utilizes following ASTM standards for testing:
| D 3335 | Standard Test Method for Low Concentrations of Lead, Cadmium, and Cobalt in Paint by Atomic Absorption Spectroscopy. |
| E 350 | Test Methods for Chemical Analysis of Carbon Steel, Low-Alloy steel. Silicon Electrical Steel, Ingot Iron, and Wrought Iron. |
| E 507 | Test Method for Aluminum in Iron Ores by Atomic Absorption Spectrometry. |
| E 508 | Test Method for Calcium and Magnesium in Iron Ores by Atomic Absorption Spectrometry. |
| E 1600 | Test Method for Determination of Gold in Cyanide Solutions by Atomic Absorption Spectrometry. |
