为进一步提高极谱分析速度,使极谱分析更好地为选矿试验和地质勘探服务,我们经过反复试验和改进,试制成一台由示差示波极谱仪[1—4]和数字电压表结合起来的一种直读示波极谱仪。该仪器是在示波管上显示出一条基线,用来测量极谱波的峰值时,数字电压表上就显示出被测元素的百分含量。这样既有示差示波极谱较高的灵敏度、准确度和测量时间很短等优点,又省去了处理分析数据的时间,对提高极谱分析速度具有良好效果。仪器经三个月的性能试验和600多个选矿试样的分析,证明仪器性能稳定,
In order to further improve the polarographic analysis speed and make the polarographic analysis better serve the beneficiation test and geological prospecting, we made a series of experiments including the differential oscilloscope polarography [1-4] and the digital voltage Table combined with a direct reading oscilloscope. The instrument displays a baseline on the oscilloscope tube, used to measure the peak polarographic wave, the digital voltmeter shows the percentage of the element under test. This has the advantages of high differential oscillopolarographic sensitivity, accuracy and measurement time is very short, but also eliminates the need to analyze the data processing time, to improve the polarographic analysis has a good effect. After three months of performance testing equipment and analysis of more than 600 dressing samples, the instrument proved stable performance,
