本文综合评述了前人所用间断雾化的各种进样方式和装置,发现在采用峰值测量时,其灵敏度和精密度差别不大。这样,可以直接将喷雾毛细管瞬间(约3秒)插入试液,进行测定。本文对影响饱和量体积的各种因素进行了较详细的试验与对比,包括提升量的变化。喷雾响应时间,不同粘度,不同溶剂(水与有机)的影响。认为饱和量体积实质上取决于待测元素到达火焰和原子化平衡的时间,以及仪器的响应速度。本文还对高盐基体的测定,有机萃取直接FAAS测定,以及血清的测定进行了研究,发现间断雾化技术在这方面具有广泛的应用前景。
In this paper, various injection methods and devices of intermittent atomization used by predecessors are reviewed, and the difference between sensitivity and precision is not obvious when using peak measurement. In this way, you can directly spray capillary tube (about 3 seconds) into the test solution, the determination. In this paper, a detailed test and comparison of various factors influencing the volume of saturated volume, including the change of the lifting volume, are carried out. Spray response time, different viscosities, different solvents (water and organic) influence. It is considered that the saturation volume depends essentially on the time it takes for the element to reach flame and atomization equilibrium, as well as the response speed of the instrument. In this paper, the determination of high salt matrix, the direct FAAS determination of organic extraction and the determination of serum were also studied. It was found that intermittent atomization technology has a wide range of applications in this area.
