COA Spec Checker Akhil Mk توسط

Reading a certificate of analysis (COA) and checking it against your specification is fiddly: the numbers are scattered across a PDF, your limits are in a spreadsheet, and the units never seem to line up. COA Spec Checker turns a lab report into a plain pass/fail review, right in a popup — no account, no network calls, no permissions.

How it works

1. Paste the values from your COA, one per line — e.g. Purity: 98.7%, Lead (Pb): 0.4 ppm.
2. Set your specification limits — for each analyte, pick a minimum (≥) or maximum (≤) limit and a unit.
3. Review every value at a glance — PASS or FAIL with the margin, NO LIMIT when a value has no limit set, and NOT MEASURED when a limit has no value on the report.

Also included

• Unit conversion (mg, g, mcg) when measured values and limits use different mass units.
• A batch calculator that scales an ingredient amount per serving to a full production batch and adjusts it for the purity shown on the COA. Copy the result in one click.
• Limits and recent inputs are remembered locally.

Privacy

Nothing you paste is sent anywhere: no account, no analytics, no tracking. All parsing and calculation happen inside the add-on popup. Your limits and last inputs are saved in your browser's local storage only.
