Determination of arsenic and lead content in catalytic reforming feedstocks, at the ppb level
Thread Content
For the detection of arsenic and lead in catalyst reforming feedstocks at levels of just a few ppb, apart from atomic absorption and ICP-MS, are there any other better methods? The detection limit of ICP is not low enough, and engineers say that the conditions required for detecting lead are very stringent; seeking assistance
In this type of trace analysis, none of the aspects – from sampling and sample preparation, to the selection of analytical methods, the actual procedure for carrying out the analysis, and data processing – can be carried out casually or easily. The sample processing methods are already listed among those analysis techniques you mentioned; they are the procedures that were optimized by the researchers who developed these analysis methods in the first place. By following these procedures strictly, the analysis data will be reliable. There is no better way for this kind of trace analysis; these methods are already quite good.
First, you need an atomic fluorescence spectrometer; following the operating instructions, it can be done. There’s also a lot of content on the internet related to this topic; you can take a look.
Hello, I work in the sales of analytical instruments. I have atomic fluorescence, atomic absorption, ICP-MS, and ICP-OES devices available; we can discuss this further :):)
