Atomic Absorption Spectroscopy
Brand: Thermo Scientific™
Model: iCE 3300 Double Beam AA Spectrometer with 100mm Universal Burner
Atomic Absorption spectroscopy (AAS) detects the concentration of a target metal in a sample by measuring the amount of light absorbed by free atoms of the target metals at high temperature flame. The detection limits range from ppm to ppb for different metals. It is a widely accepted analytical technique and is still a popular choice for trace elemental analysis in scientific researches.
