由于现在使用的LP-60型普通极谱仪的灵敏度满足不了所内外提出的要求,我们将长春应化所1972年试制的示波方波极谱仪作了一些改进,以便投入使用,为此对国内外制造的极谱仪作了一些调查,作为改进工作的参考。下面介绍几种极谱仪的性能及我们对示波方波极谱仪的改进工作,最后谈一下对极谱仪的展望。一、几种极谱仪性能的分析比较极谱仪分析性能的指标最主要的有两项,即分辨度和灵敏度。另外,仪器的可靠性也十分重要。
Due to the sensitivity of the LP-60 conventional polarographic spectrometer used today, the requirements of both the inside and the outside were not met. We made some improvements to the experimental prototype of the oscillometric square wave polarograph manufactured by Changchun Institute of Applied Chemistry in 1972 for this purpose Some surveys have been made on the polarography manufactured at home and abroad as a reference for improvement. The following describes the performance of several kinds of polarography and our improvement of the oscillographic polarographic oscilloscope, and finally talk about the prospect of the polarography. First, the performance of several kinds of polarographic analysis and comparison Computational performance of polarographic indicators are the two most important, that is, resolution and sensitivity. In addition, the reliability of the instrument is also very important.
