The phone call came at 4 PM on a Friday.
"Your Certificate of Analysis doesn't match our incoming inspection results." The customer's QC manager read the numbers: Assay showed 98.7% on their CoA, but the incoming test showed 98.2%. Had the product degraded in transit? Was there a stability issue? They'd put the shipment on hold pending investigation.
Three hours later, your QA team found the answer. The LIMS showed 98.2%. Someone had typed 98.7% into the Word template. A transposition error. The kind that happens when you're copying fifteen values from one screen to another while someone asks about the next batch. The product was fine. The certificate was wrong.
Now you're issuing a corrected CoA, documenting the error, explaining to a customer why your quality documentation can't be trusted at face value, and wondering how many other certificates went out with numbers nobody double-checked closely enough.
The 4.532 that became 4.352
It happens like this: QC approves the final test results in the LIMS. Someone exports to Excel. Or prints a report and works from paper. Someone else opens the Word template, finds the right cells, and starts typing. Assay: 99.2%. Purity: 98.7%. Moisture: 0.43%. Fifteen values, manually transcribed.
The reviewer pulls up the LIMS and checks each value against the template. Everything matches. Except one. The original said 4.532%. The CoA says 4.352%. Nobody noticed because they were checking quickly, because they'd done this a hundred times, because the digits looked close enough.
- Transcription errors: "4.532 kg" becomes "4.352 kg"
- Version control: which file is final?
- "Where's my CoA?" emails pile up
- No transcription: data pulls from database
- Linked to batch: regenerate anytime
- Instant: generated the moment release is approved
Now multiply this across every batch, product, site, and customer format. Every manually transcribed value creates another opportunity for mismatch and another value the reviewer must reconcile against its source.
Why does anyone type this data?
Every piece of data on that CoA already exists in your systems. The test results are in the LIMS. The batch information is in the MES. The specifications are defined. The release decision has been made. The data is digital, validated, approved. And then someone prints it out and types it into a Word template.
This workflow exists because systems don't talk to each other. The LIMS doesn't generate formatted documents. The document template doesn't connect to the LIMS. So humans bridge the gap, acting as manual integrations between systems that should have been connected from the start.
Generation, not assembly
Seal generates CoAs directly from approved test results. When QC completes testing and results are approved, the CoA data is ready. Click "Generate," select the template, and the document assembles itself from the database. The test result that shows 4.532% in the LIMS shows 4.532% on the CoA because it's the same data. Not a copy, not a transcription, the actual value pulled in real time. Upstream, the value entered the LIMS straight from the instrument. See instrument connectivity.
The generated value retains its source result, approved version, units, calculation, significant-figure and rounding rule, specification, and rendering field. Review can therefore prove the relationship instead of comparing separately typed values.
One format doesn't fit all
Different products need different CoAs. A sterile injectable requires different information than an oral solid dose. An API certificate looks different from a finished drug product certificate. Major customers have their own format requirements. One wants results in a table, another wants them listed, a third wants their logo on the document.
Seal supports unlimited templates. Define what data appears, how it's formatted, where signatures go. When you generate a CoA, select the appropriate template and the system handles the rest. Customer A gets their format. Customer B gets theirs. The EU market gets German-language certificates. Japan gets Japanese. Everyone gets accurate data because it all comes from the same source.
Template changes go through version control. When you update a format, historical CoAs regenerate using the template version that was active when they were originally created. The certificate from 2022 looks exactly like it did in 2022, even if today's template has changed.
From hours to seconds
The traditional process. Export, copy, review, print, sign, scan, save. Takes hours. Multiple people involved, multiple handoffs, multiple opportunities for delay. When a shipment is waiting and the CoA isn't ready, the pressure builds. Mistakes happen when people rush. The truck is idling at the dock while someone hunts for a signature.
Seal removes transcription and pre-populates a controlled certificate as results and disposition become ready. Reviewers focus on exceptions, applicability, statements, and release rather than copying fields.
For concurrent release workflows. Cell therapies, radiopharmaceuticals, anything with a short shelf life. The CoA builds incrementally as results approve. When the final test passes, the certificate is already complete. Sign and ship.
Historical access without archaeology
When a customer requests a CoA from two years ago, what happens? Someone searches the file server. They navigate through folder hierarchies hoping the naming convention was followed. They find three files with similar names and try to determine which is the final signed version. "CoA_
In Seal, every CoA is linked to its batch record. Click the batch, click the CoA, download. The system knows exactly which document was generated, when, by whom, and with what data. Regenerate on demand if needed. The historical data is preserved, and the document rebuilds from the original values using the original template version.
When auditors ask for the CoA that shipped with a specific batch, you show them in seconds. When customers ask for replacement certificates, you send them in minutes. The archaeology expedition through folder structures disappears.
Distribution without email chains
Stop emailing PDFs. Give customers secure portal access to download their own certificates. They log in, see their batches, download what they need. Every access is logged. When someone calls asking "where's my CoA?", you either see that they already downloaded it or send them a link to get it themselves. No more "let me check and get back to you."
For customers who want to automate, API access delivers CoA data directly into their systems. They don't need PDFs. They need the data in a format their incoming QC system can ingest. Seal provides both: human-readable certificates and machine-readable data from the same source.
Works with what you have
Already running a LIMS? Seal connects to LabWare, STARLIMS, Benchling, and custom solutions. Pull approved results directly from your existing systems. Your analysts keep working where they're comfortable. CoA generation happens automatically from validated data. No double entry, no export-import, no reconciliation.
For organizations running multiple LIMS across sites, Seal normalizes data from different sources into consistent certificate formats. One template definition, multiple data sources, unified output quality. The customer sees the same professional certificate whether the testing happened in Boston or Berlin.
Certificate scope is defined before generation
Material or product, batch or lot, manufacturing and testing sites, specification, market, customer, language, presentation, release type, test population, statements, signatories, delivery rule, and template applicability define the certificate request.
The system records why a template and data population were selected, including any permitted override and approval.
Reportable values are governed data products
Raw result, calculation, dilution, conversion, unit, significant figures, rounding, below- or above-range representation, textual result, replicate rule, retest or resample status, final reportable value, reviewer, and source method remain connected.
The CoA uses the approved reportable value. It never infers which result among original, repeat, corrected, or invalid values should be printed.
Specification context stays attached
Specification and version, market or customer applicability, test name, method version, acceptance criterion, unit, effective date, result evaluation, and disposition state form each reported row.
Historical certificates retain the specification in force for that batch and decision even after limits or methods change.
Statements are controlled like results
Compendial compliance, manufacture, testing, origin, animal-derived material, allergens, residual solvents, elemental impurities, GMO, irradiation, sterilization, storage, retest, shelf life, release, and other declarations retain approved text, applicability rules, evidence, language, version, and owner.
A certificate includes only statements supported for its actual material, process, site, market, and customer.
Generation freezes an evidence-backed version
Request, source result and specification versions, batch state, template version, statement versions, translations, rendering engine, generated file, reviewer, signatures, hash, and creation time form the CoA version.
Later changes do not mutate a delivered certificate. A new generation is compared with the prior version and governed as draft, replacement, copy, or amendment.
Review is risk and exception focused
Missing or pending results, specification mismatches, unusual representations, changed sources, manual entries, overridden applicability, conditional release, unresolved events, translation changes, and statement gaps appear explicitly.
Comment, response, resolution, approval, and electronic-
Amendments never erase what was issued
Reason, affected fields, corrected source record, impact, customer or authority notification, approvers, replacement certificate, superseded version, delivery, acknowledgement, and withdrawal form the amendment.
Reprinting an identical signed certificate is distinguished from regenerating a new version or correcting content.
Distribution retains recipient and delivery state
Customer, consignee, partner, authority or internal recipient; permitted products and batches; secure portal, API, SFTP, email or printed channel; file and data format; authentication; delivery; access; acknowledgement; expiry; revocation; and replacement remain connected.
Machine-readable data and human-readable rendering come from the same frozen certificate version.
CoA generation does not make the release decision
LIMS owns controlled testing and approved reportable results. Specification management owns effective requirements. Batch release owns the disposition and release evidence. Document control owns controlled templates and statements.
CoA generation assembles and governs the certificate after those source decisions; it does not turn a passing table into a product release.
The strength is field-level provenance
Every reported value and statement can be traced to the exact approved source, rule and version; every certificate to the template, review and signature; and every delivery to its recipient and acknowledgement.
That is what eliminates transcription without hiding the quality decisions behind generation.
