The ZA series atomic absorption spectrophotometer adheres to the polarization Zeeman method and dual detector real-time calibration, with the addition of Hitachi technology. The data results are excellent, stable and reliable. Atomic absorption spectrophotometer can perform metal element analysis based on the effect of characteristic radiation absorption by the ground state atomic vapor of a substance. It can sensitively and reliably determine trace or trace elements.

Polarization Zeeman background correction method is applicable to: graphite furnace/flame/hydride generation method

Tested immediately upon startup, with a more stable baseline.

High reliability data can be obtained through polarization Zeeman background correction.

Real time calibration of dual beam dual detector

Two detectors simultaneously detect the sample beam and reference beam, and the fully real-time background correction technique obtains reliable results. And there is no mechanical switching of the optical axis, resulting in higher repeatability and stability.New technology: Dual injection technology

The use of dual pore graphite tubes in graphite furnace analysis can effectively improve sensitivity. The dual pore graphite tube increases the contact area between the sample and the graphite tube, improves the thermal conductivity efficiency, shortens the holding time of the drying process, and allows for detection with a larger sample volume in the same analysis time, resulting in higher sensitivity and lower detection yield.

Automatic boiling detection function

It can improve the accuracy of the detection results. Automatically detect boiling and mark "P" after the measured value. Based on this, it can be confirmed whether boiling has occurred and the heating program can be corrected in a timely manner.

Automatic residual removal of graphite tube

It can effectively reduce sample residue and improve the accuracy and reproducibility of detection results.

There are two automatic methods for disability removal:

Heating "mode, specifying longer heating and cooling times;

Temperature program "mode, the instrument has a built-in residual temperature program, with a higher residual temperature of 3000 ℃.

Continuous injection function of automatic sampler

After inhaling the reagent with an automatic injection needle, inhale the next reagent through air, and repeat the cycle to inject all samples into a C-shaped graphite tube at once.

Can effectively reduce reagent contamination; Save 40% of injection time; To obtain the same test results, a lower amount or concentration of matrix modifier is required.
