根据国外原子吸收仪器市场粗略统计,采用各类塞曼效应背景校正技术的仪器大约占有三分之一市场份额,而国产仪器中,带有塞曼效应背景校正技术的仪器占有市场份额不足十分之一。这一情况表明,研制新一代国产塞曼效应背景校正原子吸收分光光度计是市场发展的需要。2002年底,北京瑞利分析 According to the rough statistics of the foreign atomic absorption instrument market, the instruments adopting various Zeeman effect background correction technologies account for about one-third of the market. In domestic instruments, instruments with Zeeman background correction technology occupy less than 10% one. This situation shows that the development of a new generation of domestic Zeeman effect background correction atomic absorption spectrophotometer is the market needs. By the end of 2002, Beijing Rayleigh analysis
