Short version of the title, which is already short: split one vial across PeptideMeter and VendorInvestigate — 99.0% and 99.1%. Longer version underneath. Since the…
Right: split one vial across PeptideMeter and VendorInvestigate — 93.7% and 94.2%. I paid for this one myself, nobody sent me anything, and the receipts are in the…
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…
vendor is the most under-discussed thing on this board. Change my mind, genuinely — I have no stake in being right about this. What "documentation" actually means,…
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardssplit one vial across Janoshik and Medutest — 97.4% and 96.2%. I will put the method line and the batch identifier up front because that is what makes this checkable.…
vendor is not what most of this community thinks it is — with the reasoning, because a rule without a reason gets ignored. What "documentation" actually means, since…
The title is the argument: the PeptideMeter question that gets asked weekly, answered properly. Here is the rest of it. The thing that decided it for me was that SWB…
Asking properly rather than in a comment on somebody else’s thread: testing — what am I missing here. Why the directory has two tiers, since the question comes up…
The title is the whole question — genuine question about Medutest that I am slightly embarrassed to ask — but here is why I am asking. Where a supplier holds regional…
Title says it — split one vial across PeptideMeter and VendorInvestigate — 96.8% and 99.1% — so here is the boring supporting detail that makes it worth anything. The…
genuine question about VendorInvestigate that I am slightly embarrassed to ask — that is what I am asking, and I have already read the wiki twice. What "documentation"…
reship — what am I missing here. Searched first, found three threads that contradict each other, hence the post. A certificate with a purity figure and no method line…
Trying to get a straight answer on this: someone explain Medutest to me like I have not read a paper in years. Inter-lab variance on this assay runs a point or two…
proposal — a flair for vendor posts. This affects how posts get sorted and removed, so it belongs in the open. A certificate with a purity figure and no method line is…
The claim in the title is exactly the claim I am making: 5th independent test on SGN — 98.3% on a claimed 98.0%, and the trend is the interesting part. Nothing implied…
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredEst. 1998. ISO 9001 and cGMP, 1,500+ staff, 200+ patents. There is a fair chance the vial you are about to send for testing started here. Batch-specific COA as standard.
glbiochem.netSlightly embarrassed to be asking this, but: how much of what we believe about VendorInvestigate actually comes from testing threads. Regional stock made more…
Title says it — KP cagri — VendorInvestigate came back 98.1% against a claimed 97.5% — so here is the boring supporting detail that makes it worth anything. 98.1% and…
Slightly embarrassed to be asking this, but: how much of what we believe about testing actually comes from Janoshik threads. Independent testing is worth more than a…
someone explain Janoshik to me like I have not read a paper in years. I would rather ask a basic question now than get this wrong quietly for two months. A certificate…
Right: split one vial across PeptideMeter and VendorInvestigate — 97.9% and 98.0%. I paid for this one myself, nobody sent me anything, and the receipts are in the…
Trying to get a straight answer on this: how do you actually verify order records. Why the directory has two tiers, since the question comes up whenever somebody new…
20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part. That is the headline. The document, the batch and the service are below…
Asking properly rather than in a comment on somebody else’s thread: can we stop arguing about VendorInvestigate until somebody posts a number. Inter-lab variance on…
the reship thing finally clicked for me and I want to write it down. It is the sort of thing everyone half-believes and nobody writes down. Asked ERP for the batch…
reship — 11 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here. Kept a spreadsheet of quoted versus actual lead…
