  -introtext: "<p>Absorption spectroscopy is a key instrument in the field of analytical chemistry that helps scientists understand the properties of matter.</p>\r\n"
  -content: """
    \r\n
    <p>It provides a window into the atomic and molecular domains by observing how light interacts with materials. This advanced method relies on detecting the light wavelengths that a substance absorbs to gain information about its structure and chemical makeup.</p>\r\n
    <p>Through absorption spectroscopy, researchers can unravel the complex narratives buried within the tiniest components by leveraging the distinct signatures that each atom and molecule leaves on electromagnetic radiation. This article will explore the fundamentals of absorption spectroscopy and how its potential can massively impact various industries.</p>\r\n
    <h2>The Fundamental of Absorption Spectroscopy</h2>\r\n
    <p>Absorption spectroscopy relies on a straightforward yet significant idea: when atoms or molecules interact with electromagnetic radiation, particular light wavelengths are absorbed, producing unique spectrum patterns. Through examination of these absorption patterns, scientists can infer important details about the material they are studying.</p>\r\n
    <p>First, a wide range of electromagnetic radiation, usually in the visible, infrared, or ultraviolet (UV) wavelengths, is transmitted through the sample. Certain wavelengths of the radiation are absorbed while others pass through the sample undisturbed by the interaction. The absorbed wavelengths represent changes in the energy levels of the atoms or molecules, giving each item a distinctive signature.</p>\r\n
    <h2>Advantages of Absorption Spectroscopy</h2>\r\n
    <p>Numerous intrinsic benefits of absorption spectroscopy lead to its broad use in commercial and scientific applications, including:</p>\r\n
    <ol>\r\n
    <li aria-level="1">\r\n
    <p>High Sensitivity: <a href="https://www.agilent.com/en/product/atomic-spectroscopy" target="_blank" rel="noopener">Agilent absorption spectroscopy</a> is a highly helpful tool for analyzing trace elements or compounds present in low concentrations since it can identify minuscule amounts of substances.</p>\r\n
    </li>\r\n
    <li aria-level="1">\r\n
    <p>Versatility: Absorption spectroscopy can examine a variety of substances, including gasses, liquids, and solids, due to its capacity to explore a broad range of wavelengths.</p>\r\n
