The Platform

From raw export to signed record. One controlled system.

No rip-and-replace. WLTR sits beside the instruments and LIMS you already run, ingests the exports they already produce, and returns a verified, QA-approved calibration record.

How it works
Calibration Intelligence

All nine models. Every analyte. One field of view.

The interface is structured for evidence, not decoration. Review calibration points, compare model performance, verify the ICV and accept the simplest passing model without leaving the record.

Inside the platform

Source integrity first. Approval last.

Four capabilities in a deliberate order. Humans remain responsible for decisions — the system makes those decisions inspectable.

01 · Source preservation

The record starts at the raw text — and is never retyped.

Ingest instrument output directly, parse it deterministically, and store the original text immutably with a SHA-256 hash so every downstream value traces to its source.
  • Raw instrument text parsed and hashed at upload
  • Run-type aware — an ICV can never silently enter a curve
  • An immutable source record behind every reported number

02 · Nine-model computation

All nine deterministic models. Every analyte. One view.

Compute all nine deterministic mathematical models for every analyte with simultaneous overlays — point-level %Diff, model fit and ICV recovery — without rebuilding the curve by hand.

  • All nine models computed simultaneously, server-side
  • Every level scored against the active threshold
  • The simplest passing model is recommended

03 · Review by exception

Whole-group visibility. Nothing slips through.

Aggregate calibration curves across every analyte and surface per-analyte pass/fail states, spotlighting trends and anomalies. Reviewers start with the exceptions instead of hunting for them.
  • Whole-group computation across all analytes
  • Per-analyte pass/fail triage on one screen
  • Aliases resolved once, matched automatically after

04 · Evidence attached

Audit-ready output for any inspection.

Freeze the method configuration at compute time, log exclusions with user and reason, verify the ICV, and route the completed record through a named QA approval gate.
  • Readiness validations gate every compute
  • Method config frozen — historical results never move
  • Role-separated QA approval with a named signature

The controlled workflow

From source text to signed record.

Seven steps replace the fragmented spreadsheet stage without pretending laboratory judgment can be automated out of existence.

Step 01

Configure the laboratory

Define instruments, methods, acceptance criteria, users and QA roles.
Step 02

Upload calibration and ICV runs

Capture raw instrument text, metadata and source hashes before analysis begins.
Step 03

Resolve analyte mappings

Match raw compound names to canonical analytes and preserve aliases for future runs.
Step 04

Build the calibration group

Validate level counts, duplicates, internal standards, ICV attachment and active method configuration.
Step 05

Compute all candidate models

Generate nine models per analyte and evaluate every level against the active criteria.

Step 06

Generate the evidence record

Package selected models, exclusions, ICV performance and method context into a consistent report.

Step 07

Route to QA approval

Complete role-separated review with a named approver and permanent audit timeline.

Fits your laboratory

No rip-and-replace. No new instrument software.

WLTR works from the exports your instruments already produce and returns records your QA process already expects.

Works with your instruments

GC, LC and IC systems — GC/MS, LC-MS/MS, ion chromatography — WLTR ingests the text exports they already generate. No drivers, no firmware, no vendor lock.

Alongside your LIMS

The verification layer sits between instrument and LIMS/ELN — verified records flow into the systems of record you already trust.

Inside your SOPs

Acceptance criteria, roles and approval gates are configured to your methods — the platform enforces your SOP, it does not replace it.

Accurate. Traceable. Defensible.

Watch your own data move through the layer.

Bring a representative instrument export to a 30-minute session and see the full path — source record, candidate models, ICV verification, exceptions, approval trail.
