This is the classic approach. It’s fast, relatively inexpensive, and great for measuring elements in the "parts per million" (ppm) range. It’s ideal for high-volume labs testing soil or food.
At its core, AAS is a technique used to determine the concentration of a specific metal element in a sample. It relies on the principle that free atoms in the "ground state" (their lowest energy level) will absorb light at very specific wavelengths. atomic absorption spectrometry
Checking the purity of gold or the composition of alloys during production. The Bottom Line This is the classic approach
As the light passes through the cloud of atoms, the atoms "soak up" some of that energy. The more atoms there are, the more light is absorbed. At its core, AAS is a technique used
Compared to mass spectrometry, AAS has lower operating costs and requires less expensive consumables.
Modern AAS systems are highly automated, making them accessible even for labs without specialized physics expertise.
