Method Doctor beta

Paste your peak table, tell me your column and your goal — I'll find where it's failing and how I'd fix it. Like having a senior GC analyst read your chromatogram.

How to use:

Upload a CSV (raw time,signal, or an integration report) — or paste your peak table below.
Pick your column phase and your goal.
Diagnose → the critical (worst-resolved) pair, peak capacity, and prioritized fixes, including the McReynolds phase swap.

Upload a chromatogram or peak report (CSV) — a raw time,signal trace (peaks detected for you) or an integration report. Or paste below.

Peak table — one per line: retention time, peak width (half-height, min), compound (width optional; needed for true resolution)?

Your column phase?

Goal?

Column length (m)

Advisory — a starting point, not a prescription. Recommendations are heuristic, based on your peak data + published phase selectivity. Resolution math assumes Gaussian peaks. Always confirm changes on your own instrument and standards. © MAI-Alchemy / Medrado Analytical Innovations.
