SECTION 2 CONCLUSIONS A new Zeeman atomic absorption (ZAA) spectrometer was designed and built to make continuous on-line measurements of mercury in the off-gas from oil.

In atomic absorption spectroscopy we deal with atoms at ground stage, these atoms absorb a characteristic wavelength of radiations coming from the source which is commonly a hollow cat-hod lamp.

It requires high energy and the resonance line is below nm. Koizumi and K. Uchino, “Atomic absorption analysis for mercury using the Zeeman effect,” Hitachi Hyoron, 56, No.

Zinc is determined by atomic absorption spectrometry by direct aspiration of the sample into an air-acetylene flame. The procedure may be automated by the addition of a sampler and either a strip-chart recorder or a printer or both.

on-line, gas monitor based upon the principal of Zeeman atomic absorption spectroscopy was the primary analytical method. This practice is known as atomic absorption spectroscopy (AAS).

AAS was first deployed back in by Gustav Kirschoff and Robert Bunsen to detect the presence of certain atoms in flames and gases. Since then, the modern approach to AAS has been revolutionised, most noticeably by A. Walsh and C. Alkemade in the s. An atomic absorption spectrometry for the quantification of zink (Zn) and mercury analyzer for the quantification of mercury (Hg) levels in cream cosmetic were developed and validated.

The method was validated for linearity and range, precision, accuracy, limit Cited by: 3. AtomicAbsorption 24 Zeeman Background Zeeman Background Correction is used mainly in graphite furnace atomic absorption systems. When an atom is placed in a magnetic field and its absorption of observed in polarized light, the normal single line is split into three components – б- π and б +displaced symmetrically about the normal position.

This test method can be used to determine the total mercury concentration of a natural gas stream down to μg/m can be used to assess compliance with environmental regulations, predict possible damage to gas plant equipment, and monitor the efficiency of mercury removal beds.
