what should I do if I encounter double charge interference?

That's because double charge is also a common type of mass spectrometry interference that needs to be controlled. This kind of interference is very unfamiliar to ordinary users, and the flow rate KED method generally recommended by manufacturers cannot solve it or even has the opposite effect. Below, I use a little experience and a lot of speculation to sort out the way a single quadruple rod copes with double charges. The conclusion is not important and it is purely a sharing of ICP-MS technology. If it can arouse everyone's thinking, it will be very valuable. I hope it can serve as a starting point. For the convenience of discussion, this article only takes As and Se as examples to describe.
