Direct analysis of solids for trace elements by combined electrothermal furnace/quartz T-tube/flame atomic absorption spectrometry



Direct analysis of solids for trace elements by combined electrothermal furnace/quartz T-tube/flame atomic absorption spectrometry



Analytica Chimica Acta 166: 39-49



The analysis of solid samples by a combined graphite-furnace/air-acetylene flame technique based on generally available atomic absorption instrumentation is described. Samples are injected into the furnace and atomized via a slotted T-tube in the flame. The elements considered are cadmium, lead, copper, arsenic, cobalt, mercury, antimony and selenium. Volatile elements such as mercury and arsenic can be determined without the need for a char step.
