Geological sample custody reconciliation calculator

Calculate missing IDs and unexpected IDs with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use missing IDs and unexpected IDs to compare changes to your inputs. The method and limits below explain the scope.

Assumptions & limits

Assumptions & limits

  • Sample identifiers, dispatched-received records. Returns Missing and duplicated custody events. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
