Abstract Electrothermal atomic absorption spectrometry of titanium with a tungsten tube atomizer has been investigated. Addition of hydrogen to the argon purge gas used for the titanium absorption signal in the tungsten atomizer provided narrower and more sensitive peaks than that obtained in pure argon. The optimal gas flow rate was Ar 200ml/min and $H_{2}$ 300ml/min. The characteristic mass and detection limit for titanium were 7.5pg and 7.3pg (corresponding to 0.73ng/ml, 10μl given). The interferences caused by large amounts of interferents were eliminated by high temperature pyrolysis. Geological samples were analyzed with satisfactory results.
