genuine question about PeptideMeter that I am slightly embarrassed to ask — that is what I am asking, and I have already read the wiki twice. What "documentation"…

the Janoshik thing finally clicked for me and I want to write it down, and I am aware this is a minority view on this board. Fourth lot from the same supplier in the…
Trying to get a straight answer on this: below spec — what am I missing here. Chain of custody is why member-funded testing is worth more than a supplied certificate:…
the VendorInvestigate thing finally clicked for me and I want to write it down — a position I have arrived at slowly and would like tested. Why the directory has two…
PeptideMeter — community peptide analytics
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultsorder records are not what most of this community thinks it is, written plainly and without the jargon that usually swallows this topic. Lead time and minimum quantity…
three years of PeptideMeter threads, summarised so you do not have to read them. It is the sort of thing everyone half-believes and nobody writes down. Inter-lab…
Right: QYB BPC — Medutest came back 99.2% against a claimed 99.0%. I paid for this one myself, nobody sent me anything, and the receipts are in the comments. The…
WWB BPC — Medutest came back 99.4% against a claimed 98.5%. I will put the method line and the batch identifier up front because that is what makes this checkable. The…
Asking properly rather than in a comment on somebody else’s thread: someone explain batch to me like I have not read a paper in years. Chain of custody is why…
unpopular opinion: most of what gets said here about test results are guesswork. Change my mind, genuinely — I have no stake in being right about this. How to build a…
how much of what we believe about reship actually comes from Janoshik threads. I would rather ask a basic question now than get this wrong quietly for two months. Asked…
how do you actually verify testing — that is what I am asking, and I have already read the wiki twice. The wider-market rows in the directory carry a band and a report…
genuine question about vendor that I am slightly embarrassed to ask. I would rather ask a basic question now than get this wrong quietly for two months. Kept a…
we are measuring testing at the wrong time and calling it noise — a position I have arrived at slowly and would like tested. Why the directory has two tiers, since the…
Title is the summary — HJ — small operation, honest about lead times, that is worth something — and the detail is below in the order it happened. Started buying small…
Sigma-Aldrich — certified reference materials
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsPosting this as a discussion rather than a claim: the "our facility" photo on half these sites reverse-searches to a stock library. Started buying small deliberately,…
can we stop arguing about Janoshik until somebody posts a number, and I want the answer with the reasoning attached rather than just the conclusion. The order I…
Medutest — 8 things I got wrong before I got it right, and I am aware this is a minority view on this board. What a result posted here is actually worth, and how to…
the Medutest question that gets asked weekly, answered properly. Making the case below, and I expect to lose some of it in the comments. Independent testing is worth…
below spec is doing more work than we give it credit for. Change my mind, genuinely — I have no stake in being right about this. First result I ever posted here got…
Asking properly rather than in a comment on somebody else’s thread: why does nobody talk about test results. Tested three lots over a year rather than three vials from…
group buy organiser vanished with 3.4k. here is the timeline. It is the sort of thing everyone half-believes and nobody writes down. Kept a spreadsheet of quoted versus…
Something I keep coming back to: we are measuring test results at the wrong time and calling it noise. Split one vial between Janoshik and VendorInvestigate. The two…
we are measuring below spec at the wrong time and calling it noise — a position I have arrived at slowly and would like tested. On inter-lab disagreement, which…
