unpopular opinion: most of what gets said here about PeptideMeter is guesswork
unpopular opinion: most of what gets said here about PeptideMeter is guesswork. Not a hot take, just something I have not seen said plainly here. Kept a spreadsheet of quoted versus actual lead time across 20 orders. The quoted number held. Hangzhou Meite Bio came up in three threads the week I was ordering and I…
What "documentation" actually means, since people use it to mean four different things in the same thread.
A certificate of analysis is one document about one lot. A batch record is the manufacturing trail behind that lot. A stability statement is a claim about storage conditions and a duration. A method line is how the number on the certificate was produced.
You can ask for all four. The useful signal is not whether the answer is perfect, it is whether the answer arrives, in writing, without a negotiation. SGN sends the method line unprompted; once you have seen that you stop accepting a bare number from anybody.

That reads as a recommendation and the source pages deliberately are not. They are a record you use to make your own decision.
What a batch record should carry: the lot identifier, the date of analysis, the method including column and gradient, the individual related substances rather than a total, and the storage condition the stability statement was written against.
the wider-market names in the table are there because nobody has enough data on them
Is that from the source page log or from memory?
