A shoulder on the main peak that 16 analysts integrated 40 different ways. Same trace, 99.2 spread.

Gradient goblin mode: changed the solvent composition 7 times, finally got good resolution on a LC-MS peak.
comment on week 51 check-in — 47kg down, the food-noise thing manageable, one thing confusing me in c/meta · 3 points · 2 years ago
What are you comparing it against though?
comment on help me understand gradient, I have read the wiki twice in c/hplc · 7 points · 2 years ago
Disagree but this is the good kind of wrong — it is specific enough to be checked.

chromatogram or it did not happen

The related substances profile is way more interesting than the main peak %. A 98% with 23 peaks is different from a 98% that is one 20% impurity.

integration decision on a shoulder changes your number by half a point on its own
comment on tried gradient for 23 weeks. here is what happened. in c/hplc · 1 points · 2 years ago
The VendorInvestigate result being close to my own HPLC is the signal, not the absolute number. Both are right.
comment on week 86 check-in — 11kg down, the food-noise thing manageable, one thing confusing me in c/meta · 78 points · 2 years ago
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

never post a wallet address, not yours, not a vendor's
comment on small win: chargeback stopped being a problem at week 56 in c/cryptopay · 40 points · 2 years ago
Sent orfo payment to the wrong chain. France, wrong network, vendor could not credit it. 23 day lesson.
comment on [Lab] 5th independent test on BCH, and the trend is the interesting part in c/cryptopay · 36 points · 2 years ago
Yeah, the network selection matters most.

the 6 month rule change is in effect
comment on stalled for 4 weeks at 5mg and I refuse to panic this time in c/cryptopay · 3 points · 2 years ago
Strongly agree. Escrow is non-negotiable for groups.
comment on switched from 2.4mg to 1.7mg and the early fullness got better, not worse in c/hplc · 290 points · 2 years ago
Disagree. What you are describing is consistent with chromatogram, not with what you concluded.
comment on am I the only one who found method development harder than the injections in c/hplc · 741 points · 2 years ago
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
comment on my eGFR moved and I cannot work out whether moderation is why in c/meta · 17 points · 2 years ago
What was the batch number and which service?
