Abstract

An electrothermal vaporization-hollow cathode glow discharge-atomic emission spectrometer(ETV-HCGD-AES) has been developed for detecting heavy metals in human serum and urine samples. Fisrt of all, we designed a glow discharge cell for atomic emission spectrometry and its analytical performance was studied with the standard reference materials(SRMs) purchased from the NIST. Practically, the ETV-HCGD-AES demonstrated better instrumental sensitivity and selectivity for detecting Hg and Pb in the SRMs, serum and urine, than ICP-OES since the ETV-HCGD-AES was not required the complicate sample digestion procedure, which improved sample transportation efficiency.
