1.技术要点:钽环原子化器是电热原子化方法的一种,将高纯金属钽片制成环形(见图1),以强电流、热激发使其速达高温.将待测元素原子化的一种手段.以日本岛津QV一50型单色仪为基础,组装了仪器.用稳流管稳定钽环供电电流,用PZ一8型数字电压表记录峰吸收值.此钽环原子化器的灵敏度可达1011‘克.由于加入样品溶液集中于钽环的中间槽底部位,从而严格控制了样品烤干后的
1. Technical points: tantalum ring atomizer is a method of electrothermal atomization, the high-purity metal tantalum sheet made of ring (see Figure 1), with a strong current, heat excitation to speed up to the test element atoms A method based on Japan’s Shimadzu QV-50 monochromator, the assembly of the instrument with a steady flow tube tantalum ring supply current, with PZ-8 digital voltmeter to record the peak absorption value of the tantalum ring The sensitivity of the atomizer up to 1011 grams because the sample solution is concentrated in the central trough tantalum ring bottom position, which strictly controls the sample after drying
