@Koumine I want to bring to your attention that the extract you are showing is not part of the USP <1469> chapter. The tables were part of the original proposal in Pharmacopeial Forum, but got deleted. Also, the amount of research done in the nitrosamines testing space has evolved from the original publication.
When it comes to analytical attributes I refer to the collaborative study conducted by FDA with other agencies on the testing of Nitrosamines.
