AA2300 Pneumatic Graphite Furnace Atomic Absorption Spectrophotometer AAS
Introduction of Atomic Absorption Spectrophotometer
Atomic Absorption Spectrophotometry (AAS) is used to determine the concentrations of individual elements in a sample by measuring the selective absorption of light by gaseous atoms produced by spraying a solution into a flame (FAAS) or by evaporation in a carbon tube (CFAAS). AAS is commonly used for trace metal analysis of a wide range of sample types in the environmental sciences, food and beverage, chemical and pharmaceutical sectors for impurity or contamination monitoring and quality control, as well as the rapid assessment of raw materials. It is also used in a clinical setting for the analysis of biological fluids, such as blood and urine.
