Graphite components for AAC UNICAM

Nuclear and absorbing spectrometers with electrothermal atomization are the irreplaceable tool for definition of trace amounts of chemical elements.
Sensitivity of AAS with THIS is 2-3 orders higher, than at spectrometers with ardent atomization that is reached due to carrying out process of atomization in special graphite ditches at a temperature up to 3000 of 0C.

Nuclear and absorbing spectrometers of new generation of Varian AA240Z and AA280Z! are equipped with the advanced graphite GTA-120 furnace which provides a resource a ditch to 1800 elementopredeleniye (for example for V, at a temperature of flash of 2600 0C), and for easily flying elements (for example for Cu, 23000C) to 5000 elementopredeleniye.

However the resource graphite a ditch averages about 300 elementoopredeleniye, and during the work with low concentration and easily volatile compounds to 600-1000.
