Atomic Absorption Spectrophotometer

Product Description

We are Leading Suppliers of Atomic Absorption Spectrophotometer from Coimbatore.

Atomic absorption spectroscopy (AAS) is used to analyze metal samples by determining the presence and concentration of metals in a liquid sample. Metals include Fe, Cu, Al, Pb, Ca, Zn, Cd and many more. It also measures the concentrations of metals in the samples. Typical concentrations range in the low mg/L range.

In their elemental form, metals will absorb ultraviolet light when they are excited by heat. Each metal has a characteristic wavelength that will be absorbed. The AAS instrument looks for a particular metal by focusing a beam of UV light at a specific wavelength through a flame and into a detector. The sample of interest is aspirated into the flame. If that metal is present in the sample, it will absorb some of the light, thus reducing its intensity. These instruments measure the change in intensity. A computer data system converts the change in intensity into an absorbance.
