How Agilent Atomic Absorption Spectroscopy is Revolutionising Chemical Analysis

Chemical analysis constantly changes, so precision, reliability, and efficiency are essential. Atomic absorption spectroscopy has revolutionised this field. With their cutting-edge AAS instruments, Agilent Technologies has led this revolution. Agilent atomic absorption spectroscopy is revolutionising chemical analysis, and this blog post discusses its principles, applications, and benefits.

Understanding Atomic Absorption Spectroscopy

Atomic absorption spectroscopy quantifies chemical elements by measuring light absorption by gaseous free atoms. The sample’s element concentration is determined by measuring its absorbed radiation. Its sensitivity and ability to detect elements at ppb levels make it useful for many applications.

The Working Principle of AAS

The process of AAS can be broken down into several key steps:

  1. Atomisation: The sample is converted into free atoms in a gaseous state, typically using a flame or graphite furnace.
  2. Absorption: A light source emits a specific wavelength corresponding to the interest element. As this light passes through the atomised sample, the free atoms absorb the light at that specific wavelength.
  3. Detection: The amount of absorbed light is measured by a detector, and this absorption is directly proportional to the concentration of the element in the sample.

Agilent has refined this process, incorporating advanced technologies and innovative designs to enhance the accuracy, sensitivity, and reliability of its AAS instruments.
