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.
Electrothermal Vaporization-Hollow Cathode Glow Discharge-Atomic Emission Spectrometer(ETV-HCGD-AES)를 이용하여 혈청과 뇨에 함유된 중금속 원소들의 분석을 시도하였다. 먼저 글로우 방전셀을 목적에 맞게 설계하고, 미국 NIST로부터 구입한 표준시료인 혈청과 뇨를 사용하여 미량분석을 위한 기초실험을 수행하였다. 전처리를 하지 않은 시료의 분석에서 새로이 개발한 ETV-HCGD-AES는 수은이나 납 등의 검출에서 ICP-OES보다 상대적으로 전처리가 거의 필요없었으며 감도와 선택성에서도 우수함을 관찰하였다.
