Elemental analysis techniques are methods used to determine the composition of materials by identifying and quantifying the elements present. Common techniques include atomic absorption spectroscopy, inductively coupled plasma mass spectrometry, and X-ray fluorescence. These methods are essential in various fields, including environmental science, materials science, and pharmaceuticals, as they help ensure quality and safety. These techniques can analyze solid, liquid, or gas samples, providing valuable information about the elemental makeup. By using these methods, scientists can detect trace elements, assess contamination levels, and study the properties of different substances, contributing to advancements in research and industry.
