Solutions · Audit Defensibility
Every calibration WLTR evaluates is captured, attributed and approved, with a complete trail from instrument export to final result. When the auditor asks how a calibration was accepted, the record answers.
The problem
In most labs, the evidence behind a calibration decision is assembled after the request arrives, from spreadsheets, exports and memory. Every reconstructed answer invites the next question.
The story of a batch is rebuilt days or years later, from whatever files and recollections survive.
Who chose the model, what was excluded, and why. Without attribution, there is no good answer.
One calibration finding invites a deeper look at every result built on top of it.
With WLTR
The first capture of the data is preserved and cannot be silently altered.
Every evaluation, exclusion and approval is recorded against a named person.
From raw instrument export to approved result, every step is in the record.
A standard leaves the curve with a recorded reason and a name, never quietly.
Sign-off is explicit, and the reviewer sees the same evidence the analyst did.
Output aligns with ISO/IEC 17025, NELAP/TNI, GLP and GMP expectations.
See it work
From upload to QA approval, every action is recorded against a named user with a time and a reason. This is the trail an auditor asks for, assembled before they ask.
ICAL_COMPOUND-A_RUN0412.TXT. SHA-256 recorded.Signature meaning: Approval. I have reviewed this calibration record, its exceptions and its full audit trail, and I approve it for use.
Illustrative. In WLTR, approval requires the reviewer’s own credentials, and the signature is permanently linked to this record.
One verification layer
Each solution is one view of the same verification layer. Together they turn raw instrument output into a verified, traceable, QA-approved calibration record.
We find operational inefficiencies & design the systems that eliminate it.
