When an atom is applied to a magnetic field, the atomic absorption spectrum wil l spl i t into mult iple spectra due to Zeeman effect. Light consists of polar izat ion components. Atoms in a magnet ic f ie ld absorb the l ight component polarized parallel to the magnetic field (P//), but do not absorb the light component polarized perpendicular to the magnetic field (P ⊥ ). On the other hand, molecules and particles composing the background are not affected by the magnetic field and therefore, the scattering and absorption of them lead to the same amount of decrease in the light component of P// and P⊥ . The absorption by the background can be eliminated by subtracting those two signals and thus, the only the atomic absorption signal to be measured will be obtained. Both the P// and P⊥ are measured by the beam from the same light source (hollow cathode lamp). This results in a perfect double beam spectrometry accurate background correction in the whole wavelength range.

As the lights from the sample and reference are collected simultaneously, the real-time correction is possible. In addition, Device to switch between the sample light and reference light is not required and thus, better stability and reproduc ib i l i t y as we l l as background cor rec t ion can be ach ieved. Consequently user can acquire the reliable analytical value. High reliability is the most important for analytical instrument.

By using the polarized Zeeman correction method which provides a baseline which has high stability, the analysis of Cd in brown rice at a level significantly lower than 0.4 ppm is possible even by flame analysis.

The twin injection function can measure 0.2ppb level of Sb without in-furnace concentration.* Pyrotube-D HR is required to use the twin injection function.

1. Enhanced accuracy achieved by the twin injection function.2. Data reliability enhanced by the automatic bumping detection and cuvette memory suppression functions.3. Speedy dispensing by the auto sampler.4. Improved visibility for the nozzle position adjustment and cuvette setting by the LED lighting.5. Energy saving setup during the analysis standby is possible.

* The polarized Zeeman correction is employed for all the analysis methods.* Graphite tube C HR(low cost and sensitivity compared with the Graphite tube HR),and conventional Pyro tube HR(7J0-8880)are also available.
