Online amine analyzers
Thread Content
There is a situation where DMAC is used as a solvent, and diethylamine, ethylenediamine, and diethylenetriamine are added step by step into the same container. It is necessary to monitor the concentration of these amines online at each step (titration is used in the laboratory). Since the concentrations are relatively low, a high level of precision is required. Does anyone know what type of instrument, based on what principle, could be used to achieve this? The budget shouldn’t be too high. . . Thank you in advance. . .

The budget shouldn’t be too high; it’s not the instrument manufacturers who set the budget – it’s you who do that. So you know best what amount is not too high and what amount is too high. Is 1 million too high or not? With a budget of 10 million, if it’s possible to achieve detection at the ppb level with an accuracy of 0.2%, and considering costs for sampling, sample processing, auxiliary equipment, spare parts for two years, on-site training, and training for instrument manufacturers, I don’t think it’s too high. Asking in this way makes it impossible for the person who wants to provide you with information to understand. Any analyzer has a certain range of applicability. Since you have made a request, why can’t you be more specific?
Online analytical instruments: millions, tens of millions? ? What we need, of course, are also mature products; we hope that those who have used them can offer help so that we can understand better. It cannot reach the ppb level, but a precision of 0.1% is also not sufficient. At least 0.001%. It’s an instrument around 10w I guess. .
What is the actual concentration level? Are there any explosion-proof requirements? Process temperature? Proposed installation location? (Usually, online measurement requires good fluid flow in the medium)
