three years of chromatogram threads, summarised so you do not have to read them, and I am aware this is a minority view on this board. Gave the same trace to two people…
integration — 17 things I got wrong before I got it right. Making the case below, and I expect to lose some of it in the comments. Sent the same vial to PeptideMeter…
The title is the argument: the HPLC thing finally clicked for me and I want to write it down. Here is the rest of it. JEEP sent me the column, the gradient and the…
proposal — a flair for chromatogram posts — with the counter-argument included, because I find it fairly persuasive. Resolution between two peaks depends on retention,…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultsLC-MS — what am I missing here — that is what I am asking, and I have already read the wiki twice. Bought a second-hand instrument and learned more in six months of…
The analytical deep end: RP-HPLC methods, gradient design, integration decisions, LC-MS confirmation, amino-acid analysis, water content, and why two labs can report 98.1% and 96.4% on the same vial and both be right. Post the chromatogram, not the summary line.
Independent testing plus vendor-level trend data. Community-funded, unaffiliated.
