Abstract

The electrothermal vaporization (ETV) hollow cathode glow discharge atomic emission spectrometer for analysis of liquid sample has been developed and characterized. This system has improved the sample introduction method of electrothermal vaporization and the hollow cathode glow discharge. The sample introduction method was possible to provide high analyte transport efficiency to the plasma by helix coil made of tungsten material. In addition, small volume samples (<$30{\mu}{\ell}$) could be used. The system has glow discharge cell with special design for improvement of precision. The effect of discharge parameters such as discharge power, gas flow rate has been studied to find optimum condition. The emitted light was effectively carried into detector by fiber optic cable in UV region. The calibration curve of Pb, Cd were obtained with 3 samples.

효율적인 시료의 분석을 위하여 개선된 전열증기화 속빈음극관 글로우 방전 우너자방출분광 장치를 제작하여 그에 대한 기초 연구를 수행하였다. 본 시스템은 개선된 속빈음극관 글로우 방잔에 개선된 전열증기화법을 이용한 샘플주입방법을 응용하였으며, ${\mu}{\ell}$단위의 적은 양으로도 분석가능하도록 순수한 텅스템 재질로 된 나선형 코일을 제작하여 증기화 효율을 최대한 높일수 있도록 하여 글로우 방전으로 최대한 많은 양이 주입될 수 있도록 개선하였다. 최적화된 분석조건을 위한 방전조건으로 시료운반기체 사용량과 방전 전력을 측정하였으며, 그 전에 글로우 방전셀의 냉각장치 및 내부의 구조적인 문제 여부에 따른 방출세기에 미치는 영향과 측정 정밀도를 관찰하였다. 방출되어 발생된 빛은 광전송용 광파이버에 의하여 효율적으로 검출기에 운반되도록 구성 제작하였으며, 마지막으로 본 연구결과에 의한 직선성을 관찰하였다.
