Atomic fluorescence spectrometric system%High current microsecond pulsed hollow cathode lamp%Arsenic%Selenium
A high sensitive hydride generation ( HG) atomic fluorescence spectrometric system was developed using high current microsecond pulsed hollow cathode lamp ( HCMP-HCL) as the excitation source and its performance was evaluated. Test results confirmed that the excitation source could give out intensive atomic spectral lines. System precision (RSD, n=7) was 1. 1% for arsenic and 1. 4% for selenium. Detection limits (DLs, 3) were 0. 0066 μg/L and 0. 0075 μg/L, respectively. The developed AFS system was proved to have high reliability, low detection limit and remarkable improvement of analysis capability compared with that of commercial AFS instruments.
