Abstract: A review, with many refs., is given on the main types of flow injection atomic spectroscopy couplings, namely: flow injection atomic absorption spectrometry, which is the most widely used type of atomic spectroscopic assembly; flow injection flame emission spectroscopy; flow injection atomic fluorescence spectroscopy; and flow injection inductively coupled plasma atomic emission spectroscopy. Special emphasis is placed on new instrument devices, coupling with other techniques and the use of flow injection to improve existing atomic methods.
