trueband Drift Watcher

See spectral drift before it becomes
a costly investigation.

Drift Watcher helps spectroscopy teams review changes after instrument ageing, detector changes, new raw-material lots, or seasonal moisture shifts—then keep the evidence, investigation, and decision connected.

Passive folder watching

New scans arrive.
Your review is ready.

Choose a local folder for compatible exports. While Drift Watcher runs, it checks for new files and brings supported scans into the local workspace. New arrivals appear beside your saved reference, ready for review.

The review never has to lose its thread.

Start with historical spectra. Let a watched folder bring later scans into view. Follow the measured difference through review, a recorded response, and a report.

One review.
Six connected views.

Start with historical scans, then let a watched folder passively bring supported new files into the local workspace while Drift Watcher runs. Arrival notices show when there is new work to review.

Scientific integrity

Differences are evidence.
Possible reasons are questions.

Drift Watcher presents measured spectral differences and recorded context for review. Signals and associations can guide the next investigation; they do not establish cause or a release decision.

Regulated-environment position

Preserve review context without overstating compliance.

Drift Watcher keeps spectral work local, preserves saved investigation revisions, records selected domain events in an append-only local history, and exports saved evidence.

Clear product boundary

trueband does not currently claim 21 CFR Part 11, GMP or GxP compliance, compliant electronic signatures, validated-system status, or customer process validation.

Questions before a trial

Fit, boundaries, and next step

Does it replace calibration software?

No. Drift Watcher supports comparison and investigation of spectra. It does not validate the prediction accuracy of a calibration model.

Can it watch a folder for new scans?

Yes. While Drift Watcher is running, it checks a selected local folder for supported new exports, adds readable scans to the local workspace, and shows new arrivals for review. Optional desktop notifications depend on operating-system permission; this is not a cloud monitoring service.

Where are spectra stored?

Imported spectra and review records remain in the local application workspace. Sign-in, entitlement checks, and product updates use defined network services.

What does the trial include?

Start the 30-day trial through the online sign-up. The included example workflow and tutorial support a self-guided start, with email product support available for software questions. A demo is available on request.

How do I get the installer?

Trial installers are provided after online sign-up. Customers with an active subscription can also use the installer portal.
