CAS :
nature : a non-flame atomic methods for atomic absorption spectrometry. The use of high-current (up to 500) The graphite tube generated by up to 3,000 ° C temperature specimen atomization. Both within and outside of inert gas (argon), the protection of graphite tube is not oxidized and ablation. Atomic process into dry, ash, ball four and purification stage, by computer control, in accordance with the procedure automatically. Advantages of the atomization efficiency as high as 95%, the sample less consumption; Free atoms in the light path average residence time is more than a second, about the flame atomization of the 1000 Act times, high sensitivity, absolute detection limit 10-12- 10-14 grams; Volatile suited to hard, hard atomic elements and trace analysis of samples. Drawback is the results of the analysis by flame atomic precision than the law is poor and the more serious memory effect, to stray light of background interference so strong correction.
