three years of integration threads, summarised so you do not have to read them

Questionbranch of 6 comments

Been lurking in c/progresspics for about 17 months and finally have something worth posting. Short version: week 39, 12.5mg, and chromatogram is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 23 threads, and the answers split roughly down the middle. What I actually want…

a round-robin on baseline integration would be genuinely useful

I am going to push back on this slightly.

About c/hplc

The analytical deep end: RP-HPLC methods, gradient design, integration decisions, LC-MS confirmation, amino-acid analysis, water content, and why two labs can report 98.1% and 96.4% on the same vial and both be right. Post the chromatogram, not the summary line.

c/hplc rules
  1. Chromatogram or it did not happen. Axis labels included.
  2. State the method: column, gradient, detection wavelength, injection volume.
  3. Area% is not mass%. Posts that conflate them get a correction flair, not a removal.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
