Method validation studies
One study per method, four sections, one audit trail. Each page below opens the workbench on that section's tab — following a link here starts a new study. It is the tabs inside a study, or a saved study's ?study= link, that carry work across sections. Fill in whichever sections your protocol calls for, then export the record or the auditor-ready PDF report. The calculations are the same engine as the free calculators, certified against the NIST reference datasets.
The report your auditor sees
Download the sample report (PDF)Every study ends in one PDF report: the inputs, the fitted statistics, each acceptance criterion printed beside its verdict, and the audit trail — page-numbered, with the study named on every sheet.
Sample layout — your study data fills this report.
Linearity
Calibration levels with replicates: the fit, the residual plot, LOD/LOQ and the verdicts, live.
Open study
Accuracy
Spike levels against the native result: per-level recovery, %RSD, confidence bounds and the AOAC expected band.
Open study
Repeatability
Replicates from one run: mean, SD, %RSD and the confidence interval on the mean, judged against the guideline.
Open study
LOD / LOQ
A slope and whichever σ your method supports: every detection and quantitation limit route ICH Q2(R2) accepts, side by side.
Open study
Every section works without an account. Saving a study and the PDF report are what a plan pays for — see pricing.
