comment on [Failure] gel pack arrived liquid and warm. photos at unboxing. in c/coldchain · 6 points · 5 days ago
Mechanistically the bit that matters is stability. It explains most of the early profile and a decent chunk of the outcome.
comment on [Correction] you cannot report area% to two decimals off that baseline in c/hplc · -40 points · 6 days ago
state the method: column, gradient, detection wavelength, injection volume
comment on [Discussion] AU and NZ get lumped together and the systems are nothing alike in c/glp1aus · 5 points · 7 days ago
Stalled for 6 weeks, changed nothing, and it started moving again on week 66.
comment on bought a second-hand HPLC. worst best decision of my life. AMA in c/hplc · 10 points · 10 days ago
Detection wavelength? purity and that changes at different wavelengths.
comment on [Long Term] found my lowest effective dose by going down, not up in c/maintenancephase · 7 points · 11 days ago
Every time this gets posted it hits the front page and every time someone has to re-explain it.
comment on ghost peak turned out to be plumbing. always plumbing. in c/hplc · 5 points · 14 days ago
This is the correct method framing. Column and gradient are load-bearing fields.
comment on [Discussion] we have no vocabulary for success that is not a number going down in c/maintenancephase · 27 points · 17 days ago
Strongly agree. Lowest effective dose is a real discovery process.
comment on does compounding actually matter or is it forum lore at this point in c/glp1aus · 1 points · 19 days ago
TGA shortage notices are temporary
comment on integration vs method development — genuinely asking which matters more in c/hplc · -37 points · 24 days ago
state the method: column, gradient, detection wavelength, injection volume
comment on stalled for 12 weeks at 1.0mg and I refuse to panic this time in c/hplc · 34 points · 29 days ago
integration decision on a shoulder changes your number by half a point on its own
comment on someone explain chromatogram to me like I have not read a paper in years in c/hplc · 15 points · 1 months ago
Half-life is about 168 hours, so steady state lands around week 24–5. Practical consequence: what you feel in week 1 is not what that dose does.
comment on the Netherlands: stability, and what it actually costs here in c/coldchain · 36 points · 1 months ago
gel packs last 24 hours, after that you are relying on the box itself
comment on clothes fit the same for 14 months and it is genuinely strange in c/maintenancephase · 29 points · 1 months ago
state how long you have been at maintenance, week 13 is not maintenance
comment on three years of HPLC threads, summarised so you do not have to read them in c/hplc · 160 points · 1 months ago
Gradient goblin mode: changed the solvent composition 19 times, finally got good resolution on a integration peak.
comment on three years of HPLC threads, summarised so you do not have to read them in c/hplc · 54 points · 1 months ago
Yeah, the chromatogram profile matters more than the headline number.
comment on my eGFR moved and I cannot work out whether LC-MS is why in c/hplc · 97 points · 1 months ago
the gradient is doing the separation work, not the column alone
comment on [PSA] New Zealand is not what most of this community thinks it is in c/glp1aus · 9 points · 1 months ago
The confident tone is doing a lot of work that the evidence is not.
comment on switched from 0.25mg to 1.7mg and the constipation got better, not worse in c/maintenancephase · 31 points · 2 months ago
regain is not a moral failing
comment on unpopular opinion: purity is massively overrated in c/hplc · 19 points · 2 months ago
Strongly agree. Largest single impurity tells a different story than total purity.
comment on 6 months in and gradient is still the thing I get wrong in c/hplc · 20 points · 2 months ago
the detector wavelength matters more than people think
