Results entry — chromatography

Import the detector export for a run, integrate it, and compare the measured trace against the compound's reference profile (the expected retention behavior on the house method). The output is a batch record whose chromatogram is the instrument's own data.

Data integrity rule. The certificate figure is rendered only from an imported instrument export, and every batch record carries the SHA-256 of that source file. Reference profiles are expected-value overlays derived from method calibration — they are drawn dashed, labeled, and never stored or displayed as a measurement.

1 · Sample

Identify the lot under test. The compound selection loads the matching reference profile (expected RT, acceptance window, named impurities) from peptides.json.

2 · Instrument export

Drop the chromatogram export from the data system — Agilent ChemStation/OpenLab CSV, Shimadzu LabSolutions ASCII, EZChrom-style single-column ASCII, or any text export (.exp included) with a time/signal table or a sampling-rate header. The file is parsed locally; nothing is uploaded. Binary native files can't be read — use the data system's text/ASCII export.

The example is synthetic and watermarked — records built from it cannot be exported.

3 · Trace & integration

The solid trace is the imported run. The dashed overlay is the reference profile for the selected compound, scaled to the main peak for visual comparison; the shaded band is the RT acceptance window. Adjust integration below — excluded peaks are kept in the record, marked excluded.

4 · Checks

Computed from the integrated trace against the reference profile and house specs. A FLAG does not block the record — it is recorded as a flag for analyst review.

5 · Batch record

The record bundles the raw trace, the source-file hash, integration results, checks, and sample metadata. It is the artifact the certificate and the public Verify page are generated from.
