Atomic Absorption Spectrometry (AAS) is a simple and rapid technique for analyzing elements in solution.

The atomic spectrophotometer is commonly used in water, beverages, mining operations, clinical research, and pharmaceutical analysis.

What is an atomic absorption spectrophotometer?

An atomic spectrophotometer is an analytical instrument that uses Atomic Absorption Spectroscopy (AAS) to determine the concentration of metallic elements in a sample. The elements in a liquid or solid sample are detected by different wavelengths of radiation absorbed by different atoms.
