一、前言火花源质谱分析具有高灵敏度,同时测定多元素和测定较快的特点。目前,广泛用于高纯金属材料、高纯半导体材料、激光材料、矿物、土壤、生物、水质、月球样品诸方面分析测定中,是一种较好的分析方法。火花源质谱法在国内大多数工作为半定量分析,用在水质定量分析尚未见报导。国外应用火花源质谱于水质分析的报导亦不甚多。资料采用静电滴样法,测定水中的Be、Cr、Cu、As、Si、Pb和S,灵 I. Introduction Spark source mass spectrometry with high sensitivity, simultaneous determination of multiple elements and rapid determination of the characteristics. At present, it is widely used in high purity metal materials, high purity semiconductor materials, laser materials, minerals, soil, biology, water quality, moon samples and other aspects of the analysis and determination, is a better analytical method. Spark mass spectrometry most of the work in the country for the semi-quantitative analysis, quantitative analysis of water quality has not been reported. Foreign applications of spark source mass spectrometry in the report is not much. Data using electrostatic droplet method, determination of water Be, Cr, Cu, As, Si, Pb and S, Ling
