I am looking for information on chloride suppression when analyzing for nitrite. I seem to recall finding something recently that I now cannot locate where silver was used to precipitate the chloride. I want to say that it referenced silver sulfate but I’m not certain. Does anyone have information or thoughts on this concept in sample preparation for excipients?

There is an article published by Thermo Fisher Scientific on this. It is the UV method. I have attached the link in which this article is available for your reference.
