comment on [Discussion] the crypto advice in here is 2 years out of date in c/cryptopay · 173 points · 2 years ago
Confirmations are the count of blocks built on top of the one containing your transaction. Until there are some, the transaction is not settled in any meaningful sense.
comment on [Lab] KP cagri — VendorInvestigate came back 98.1% against a claimed 97.5% in c/hplc · 1.2k points · 2 years ago
System suitability — repeat injections, tailing factor, plate count, RSD on area — is what tells you the instrument was fit for the measurement that day. Without it, the purity figure is unanchored.

Careful. A four-week stall is inside normal variation and treating it as failure is how people escalate for no reason.
comment on chromatogram is the most under-discussed thing on this board in c/hplc · 12 points · 2 years ago
Yes — system suitability first. Without it the number is an assertion about the instrument, not the sample.
comment on three years of USDC threads, summarised so you do not have to read them in c/cryptopay · 39 points · 2 years ago

Agreed — and the hash is the receipt. Nothing else is.
comment on 14 months in and titration is still the thing I get wrong in c/semaglutide · 229 points · 2 years ago
sulphur burps made the first fortnight rough at each step up, then flattened out. Predictable enough that I started planning around it.
comment on how much of what we believe about HPLC actually comes from gradient threads in c/hplc · 1 points · 2 years ago
Correcting myself upthread: I said the gradient was linear and looking again it has a hold in the middle.

Small fix — 214nm, not 210. It matters for the comparison you are making with the other run.

Bought a second-hand instrument and learned more in six months of fixing it than in three years of reading traces.
how much of what we believe about HPLC actually comes from gradient threads, and I want the answer with the reasoning attached rather than just the conclusion. Gave the…

Group buys concentrate custody, payment and communication in one person with no structure behind it. That is not an accusation about anyone — it is a description of the risk shape.

you cannot report to two decimals off that baseline

Sent the same vial to Janoshik and Medutest. 97.8% against a claimed 97.5%. The difference was the gradient, not the material.

Correction: that is a tailing factor, not a plate count. Different diagnostics for different problems.
gradient — 17 things I got wrong before I got it right. I have gone back and forth on this for months. Gave the same trace to two people I trust and got two…
