WebAtomic absorption spectroscopy (usually referred to as AAS) is an analytical technique used to measure the concentrations of elements in a sample. It is incredibly sensitive and can even detect down to micrograms (μg). Clinical analysis – it is used to analyse the metal found in biological fluids, such as urine and blood. WebAtomic Absorption Spectroscopy ( AAS) is a technique used to determine the elemental makeup of a liquid or solution. It relies on the physical principle of light absorption and is a versatile and cost-efficient method for detecting the metallic elements present in a sample.
