英文摘要	A system of atomic and ionic fluorescence spectrometry in microwave plasma torch (MPT) discharge excited by high current microsecond pulsed hollow cathode Lamp (HCMP HCL) has been developed. The operation conditions for Ca atomic and ionic fluorescence spectrometry have been optimized. Compared with atomic fluorescence spectrometry (AFS) in argon microwave induced plasma (MIP) and MPT with the excitation of direct current and conventional pulsed HCL, the system with HCMP HCL excitation can improve AFS and ionic fluorescence spectrometry (IFS) detection limits in MPT atomizer and ionizer. Detection limits (3sigma) with HCMP HCL-MPT-AFS/IFS are 10.1 ng(.)mL(-1) for Ca I 422.7 nm, 14.6 ng(.)mL(-1) for Ca II 393.4 nm, and 37.4 ng(.)mL(-1) for Ca II 396.8 nm, respectively.
