On the issue of interference in voltammetric polarography analysis
Thread Content
Several experiments have been conducted recently, and during the analysis it was found that there are many stray peaks in the voltammetric polarography results – a very large number of them. Using the sample as it is presents no problems; only one peak appears, and the consistency across the three repetitions is very high. However, there were too many stray peaks in the intermediate samples of the experiment, suggesting interference from certain substances. After analysis, the voltage setting range is only ±0.05, which should meet the requirements. I want to know where I can look up the redox potentials of various substances? Or were there some mistakes made during this process?
1. If the result is as expected with no interference from spurious peaks, it indicates that instrument i is functioning properly. 2. The experiments you mentioned – were they synthesis experiments, or were tests conducted on the original material itself, or was the original material subjected to some kind of reaction? 3. If a chemical reaction takes place, it’s normal for impurities to be introduced. Therefore, it would be helpful if you could describe the problem more clearly, so that relevant experts can offer assistance
