DISK-ENDED ATOMIZER FOR GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY

The Disk-Ended Atomizer (DEA) is a technique for spatially isothermal atomization with an improved temporal isothermality of the atomization zone. It was developed at Sofia University as a continuation of our 1, 2 studies concerning one of the most important problems of graphite furnace atomic absorption spectrometry - the problem of isothermal atomization. DEA has a simpler design then many other techniques for isotherma1 atomization (L'vov cuvette, Woodriff 4, 5 6 furnace, capacitive discharge technique, two-step 2, 7, 8 furnaces, etc.) and can be readily used with any commercial spectrophotometer. © 1990, Taylor & Francis Group, LLC.
