| Product Description | Graphite Atomic Absorption Spectrophotometer PG990G
Unique graphite furnace design, the use of advanced transverse heating graphite furnace technology, to achieve uniform graphite tube temperature, reduce chemical interference and memory effect, which can not only ensure the improvement of atomization efficiency, but also prolong the service life of graphite tube, to ensure the accuracy of analysis. |
| Features | ◆ Easy-to-use software
– Automatic positioning and optimization of each hollow cathode lamp – Control the Czerny – Turner Monochromator – Locate the wavelength and select the peak – Control the electronic parameters of the photomultiplier tube detector and hollow cathode lamp current – Balance the absorbance and background energy – Control the ignition of the flame – Optimize the best heating program ◆ Integrated safety precautions for user protection by following: – Gas leak Sensor – Power Loss Protection – Circulation Water (graphite) – Over Temperature Sensor (graphite) ◆ Precision accuracy with integrated correction system ◆ Life cycle value, best choice for less than 8 elements of analysis |
| Principle | The elements are heated and atomized in the pyrolytic graphite furnace, and become atomic vapor in the ground state, which selectively absorbs the characteristic radiation emitted by the hollow cathode lamp. Within a certain concentration range, its absorption intensity is proportional to the content of the element to be tested in the test solution.
