Atomic Absorption Spectroscopy (AAS)

Atomic Absorption Spectroscopy (AAS)

Atomic Absorption Spectroscopy (AAS) is a powerful technique used for the quantitative determination of metals. At Synergy Health Utrecht, we offer this specialized test with a focus on delivering precise measurements of metallic elements across various samples. Our expertise in AAS ensures accurate analysis, making it an invaluable tool for assessing the quality and safety of your products.

The principle of Atomic Absorption

Atomic Absorption is the fundamental principle behind Atomic Absorption Spectroscopy (AAS). In this technique, a sample is atomized, which means it is transformed into free atoms in the gas phase. These atoms then absorb light at specific wavelengths unique to each metal, creating a distinctive absorption spectrum. By measuring the amount of light absorbed, the concentration of the metal in the sample can be accurately determined. This method is renowned for its precision, enabling the detection of trace amounts of metals effectively..

Emission Spectroscopy: a comparative technique

Unlike Atomic Absorption, Emission Spectroscopy (AES) analyzes the light emitted by excited atoms. When atoms are energized to higher energy levels, they release light as they transition back to their ground state. This emitted light’s wavelength and intensity can be used to identify and quantify elements in a sample. Emission Spectroscopy is particularly effective for detecting elements at very low concentrations. However, it is generally less precise than Atomic Absorption, which is favored for its specificity and lower detection limits.

Enhancing sensitivity with a hydride generation system

A hydride generation system can significantly enhance the performance of Atomic Absorption Spectroscopy (HGAAS). It is especially useful for analysing elements like arsenic, selenium, and antimony, which form volatile hydrides when reacted with specific chemicals. This system converts the sample into a gaseous form, enabling more efficient atomization and boosting the sensitivity of AAS measurements. By minimizing potential interference from other elements, it ensures more accurate and reliable results, making it ideal for trace-level analysis.

Applications of AAS at Synergy Health Utrecht

Synergy Health Utrecht leverages Atomic Absorption Spectroscopy (AAS) for a variety of applications across different industries. The technique’s ability to detect and quantify metals with exceptional precision is crucial in ensuring product safety and compliance. AAS offers the high accuracy and sensitivity required for tasks that demand stringent control of metal concentrations, providing reliable data in even the most trace-level analyses..

The process of AAS: from sample preparation to analysis

The process starts with sample preparation, where the sample is typically digested or dissolved in a suitable solvent. Next, the prepared sample is introduced into the AAS instrument for atomization. A beam of light at a specific wavelength is then passed through the vaporized sample, and the instrument measures how much light is absorbed by the atoms. This data is analyzed to determine the metal concentrations present in the sample, providing precise and reliable results.
