摘要:

The use of a Thermospray (TSP) in flame atomic absorption (FAA) increases sensitivity. Experimental data showed that a 75 μm orifice and 0.05 cm 1D capillary produced a sensitivity increase of about 104compared to commercial flame atomizer. The signal was independent of power input over a considerable power range.
