Field-tested calculators pulled from the Alchemy platform. No install, runs in your browser, your data never leaves it.
Paste your peak table, name your column and goal — get the critical pair, resolution, and prioritized fixes (including the McReynolds-grounded phase swap). The expert, on call.
Estimate column polarity, dead time and oven ramp straight from your peak list — no method metadata needed.
Fit linear / through-origin / quadratic curves. Get slope, RRF, R², LOD/LOQ — and predict concentration.
Solve A = εbc for any variable, convert %T ↔ absorbance, and build ε from standards.
Predict RI / MW / RRF / boiling point from a 12-band VUV fingerprint across ~12,000 compounds.
Cross-vendor phase equivalency (DB-5 ≈ Rtx-5 ≈ HP-5) — find your column and every alternative.
Predict a response factor from compound class + VUV fingerprint when you have no standard.
Density ↔ SG ↔ API, molarity ↔ normality, and checking titrant normality by densitometry.
Kovats retention index from n-alkane anchors — and a name/CAS property lookup.
Advisory tools. Outputs are estimates to guide method development — always validate on your own instrument and standards. © MAI-Alchemy / Medrado Analytical Innovations.
