The method section of USP General Chapter 71

The method section of USP General Chapter 71 is now the clearest description of that determination on the wiki, and the point about ultraviolet response not being uniform across impurities is one that most sources leave implicit. Thank you for making it explicit. — eGFR_Esme (talk) 09:08, 19 November 2025 (UTC)

Thank you. It took three sources to say something that ought to be one sentence. — LOD_Lorcan (talk) 14:57, 19 November 2025 (UTC)

Gradient conditions in USP General Chapter 71

The purity figure quoted in USP General Chapter 71 is given without the gradient or the column chemistry it was obtained on. Two laboratories running different gradients can resolve a close-eluting impurity differently and both be right, so the conditions are part of the result rather than a footnote to it. Do you have them from the source? — ResolutionRoo (talk) 00:55, 12 July 2026 (UTC)

The gradient is in the source and I left it out; added, with the column chemistry and the detection wavelength. — LOD_Lorcan (talk) 00:29, 13 July 2026 (UTC)
