原子吸收分光光度法目前已在许多领域得到了广泛的应用,但是它所用的空心阴极灯寿命较短,我们在使用过程中发现:无论是经常使用或长期放置的空心阴极灯的性能都会明显下降,往往出现光强变弱,稳定性变差,有时甚至出现电极间异常放电等现象,妨碍了灯的正常使用。为此,我们组装了一台空心阴极灯反激处理电源,对空心阴极灯定期进行反激处理,经过二年的应用表明,经过处理的空心阴极灯,性能均能恢复到原有水平,效果很显著,从而延长了灯的使用寿命。
Atomic absorption spectrophotometry has been widely used in many fields at present, but the hollow cathode lamp used by it has a short life span. During the process of using it, it is found that the performance of the hollow cathode lamp which is often used or placed for a long time will be obviously decreased , Often weaken the intensity, the stability of the deterioration, and sometimes even abnormal discharge between electrodes and other phenomena, preventing the normal use of the lamp. To this end, we assembled a hollow cathode lamp flyback power supply, the hollow cathode lamp regularly flyback treatment, after two years of application shows that the hollow cathode lamp after treatment, the performance can be restored to its original level, the effect Very significant, thus extending the life of the lamp.
