Models XGY1011A and AF-640 Atomic Fluorescence Spectrometer is widely used for analysis of elements such as Zn, Sb, As, Bi, Hg, Se, Cd, Sn, Te, Ge and Pb.
The main purpose of this laboratory is to qualitative and quantitative analysis of aqueous, geochemical and mineralized samples and even if possible, biological samples.
Atomic Fluorescence Spectrometry is based on atomization of samples with heat released by electrical current. This method offers high sensitivity for analysis of 5 to 10 elements.
Atomic Fluorescence Spectrometry is a modern analytical technique, based on Absorption and Emission Spectroscopy, which are extensively used for analysis of elements such as gas Hg, Cd and Zn.
Advantages:
1. Simple structure
2. High sensitivity
3. High reproducibility
4. Low interference
5. Broad spectral source
6. High analytical speed
Atomic Fluorescence Spectrometry is the best technique used for analysis of trace and ultra trace elements.
Applications:
Analysis of elements such as Se, As, Hg, Pb and Cd in aqueous samples, food industries, cosmetics, biology, agriculture and medicine, geochemical explorations and metallurgy industry.
In this technique, samples are prepared by acidic digestion process in a hot water bath and then are analyzed.
Other accessories: Autosampler
