Mining Sample Chain of Custody Logbook

Record the chain of custody from sampling to packing, transport, and lab receipt in one browser-only workspace.

Generate sample IDs, handover logs, print-ready labels, and QR payloads while keeping sensitive details on the device.

All processing stays in this browser and no sample record is sent to a server.
QR content is readable by anyone. Keep sensitive details in summary or id-only mode.

How to use

  1. Enter the project code, site code, sample type, and collection time to generate a sample ID.
  2. Add handover events and update the seal number, current holder, and destination lab as the sample moves.
  3. Choose a label template and QR payload mode, then review the preview before exporting.
  4. Save the record locally when you need a reusable snapshot for the same site or campaign.

Samples

Track a drill-core sample from field collection to handover

Input: projectCode=K25, siteCode=DDH18, sampleType=drill_core, sampleSequence=1, collectionDatetime=2026-03-26T09:15, collectorCode=OP-14, sealNumber=S-218, labelTemplate=field

Output: Generates K25-DDH18-20260326-001 and packs the collection-to-receipt chain into a summary QR.

Switch to a short lab-receipt label

Input: projectCode=GC7, siteCode=PITN3, sampleType=rock_chip, sampleSequence=24, labelTemplate=lab_receipt, qrPayloadMode=id_only

Output: Uses an ID-first label and a minimal QR payload to keep intake scans stable.

Frequently asked questions

What format does the sample ID use?

The default format combines project, site, date, and sequence. Advanced settings can switch to a custom pattern.

Can the QR include every handover event?

Yes. The default is summary mode so the QR stays easier to scan, and full mode is available when you need the whole trail.

Can I enter personal names?

You can, but field operations usually work better with operator codes and recipient codes. QR content should always be treated as readable by anyone.

Is anything sent to the cloud?

No. Processing stays in the browser, and saving is limited to explicit local actions.
