[Lab] 18th independent test on SWB — 99.4% on a claimed 99.0%, and the trend is the interesting part
Numbers in the title, numbers in the post. 18th independent test on SWB — 99.4% on a claimed 99.0%, and the trend is the interesting part. Numbers, in the order they matter: 99.4% and 99.0%. Gave the same trace to two people I trust and got two integrations about a point apart. That was the most educational afternoon…
Retitled: the original claimed a comparison the post does not actually make.
A shoulder that does not baseline-resolve cannot be quantified honestly. You can report it as an unresolved shoulder, which is useful information, or you can develop the method until it resolves.

Agreed. And the corollary is that the method line on a certificate is not decoration, it is the number’s provenance.
Is that baseline drawn by the software or by hand?

chain_confirm_c is right — the integration choice is a decision and it should be stated alongside the result.
That figure cannot be quoted to two decimals off that baseline. The precision is not in the data.
I would not blame the sample yet. Everything you have described is consistent with the column rather than the vial.

Adding one practical thing — run the blank. It answers this before anyone has to argue about it.
