Abstract

In this study, the hydride vapour generator inductively coupled plasma mass spectrometry (HVGICPMS) was applied as the new analytical method to show the high accurate and reproductive data analysing the amounts of selenium and germanium being existed inside a system of plant. In order to decrease the interference effects, such as ion and molecular interference. Mini torch was used into the ICPMS instead of the conventional torch. At conditions of the different kinds and concentrations of acid solution, the different reductive conditions for composing hydride, and the different methods for making ash, the contents of selenium and germanium in lettuce were analysed. The inspection of yields and data comparison from SRM-1574 and -1570a were used for increasing the accuracy of this analysis.

식물 체중에 포함되어 있는 항산화제로서 주목받고 있는 게르마늄과 셀레늄의 극미량 분석에 있어서의 재현성 있는 분석방법을 제시하고자 수소화물생성장치와 유도결합플라스마질량분석기를 이용하여 분석하였다. 유도결합플라스마질량분석기에 일반적으로 사용되는 torch 대신 에너지 밀도를 높여 이온 간섭, 분자이온 생성 등의 간섭현상을 줄일 수 있는 mini torch를 사용하여 산 종류와 농도의 영향, 수소화물의 생성을 위한 환원조건, 시료 전처리 방법의 차이 등 다양한 조건하에서 상추 중의 게르마늄과 셀레늄을 분석하였다. 분석의 정확성을 평가하기 위하여 회수율 검증과 셀레늄의 표준시료인 SRM-1547, 1570a을 분석하여 기준 값과 비교함으로서 분석의 정확성을 평가하여 다음과 같은 결론을 얻었다.
