Abstract
Analytical figures of merit for nine elements (viz. Ag, Cd, Pb, Ni, Be, Fe, Bi, Cu, and P) are presented that serve to broadly characterize the furnace atomization plasma emission spectrometry technique. Detection power lies in the low picogram region; precision of replicate signals obtained with injection of samples by hand ranges from 2.2 to 12.1% relative standard deviation and the linear range of calibration spans 2-4 orders of magnitude. Relative sensitivities of alternative atom and ion lines are given for each element. Sufficient energy is available to efficiently detect analyte ion lines having excitation energies of up to 13 eV. Static and dynamic background spectra are presented which reveal broad-band contributions from molecular species such as CO, N{sub 2}, NO, and OH as well as atom lines from the He support gas.
