Quality & COA (Certificate of Analysis)

A COA is a document that summarizes analytical methods and results for a specific batch/lot. In research environments, it supports QA/QC workflows and improves reproducibility.

What a COA should include (minimum)

  • Batch / Lot number that matches the label/packaging
  • Material identification (name + internal reference code; CAS if applicable)
  • Analytical methods (e.g., HPLC, MS, NMR) and key test conditions
  • Results (purity and relevant indicators; detection limits when available)
  • Impurity profile or statement on limits (if provided)
  • Date of analysis and expiry/stability note when applicable
  • Authorized signature or digital validation from the testing laboratory
Best practice: Keep the COA attached to an internal receiving log (date received, condition check, photos if needed, storage location) so it’s audit-ready and easy to reference.

Common mistakes

  • COA shared without matching lot number
  • “Purity” stated without method or test conditions
  • No mention of detection limits / measurement uncertainty
  • Missing impurity context or traceability to the batch
Example: internal COA receiving check (educational)

Verify that the lot matches the label, confirm storage conditions, record a receiving inspection note, and file the COA using a consistent naming convention (e.g., MAT-2026-01_BATCH14_COA.pdf).

Common Risks in Research Procurement

Many inconsistencies come from traceability gaps, not necessarily from the material itself.

Risk 1: Limited traceability

Without batch tracking and chain-of-custody records, deviations are difficult to investigate and reproduce.

Risk 2: Incorrect storage

Temperature swings, moisture, and light exposure can influence stability and introduce variability.

Risk 3: Incomplete documentation

Missing SOPs and receiving logs can complicate audits, troubleshooting, and training.

What you can improve immediately

  • Create a simple receiving checklist (batch, label, condition, storage, photos if needed)
  • Maintain a material ledger (batch, date, supplier, storage, responsible person)
  • Use a basic SOP for opening, aliquoting, labeling, and returning to storage

Storage & Handling

Proper handling reduces degradation and supports consistent research workflows. The following are general, non product-specific guidelines.

General guidelines

  • Label clearly: batch/lot, received date, internal reference code, storage instructions if known
  • Minimize repeated freeze–thaw cycles by using aliquots
  • Reduce unnecessary exposure to light and humidity when relevant
  • Use temperature monitoring for sensitive materials
  • Document opening dates and any deviations from expected conditions
Note: “Stable” doesn’t mean indefinite. Record opening timepoints, aliquot usage, and any observed changes.
Template: simple storage/handling SOP (educational)

1) Receive & inspect → 2) Record batch + condition → 3) Store under documented conditions → 4) Use aliquots → 5) Log each access → 6) Return promptly to storage → 7) Document deviations.

Documentation & Traceability

Good documentation makes research more reproducible and audit-ready.

Minimum internal records to keep

  • Purchase/receiving log: date, supplier reference, batch/lot, quantity, storage location
  • COA archive linked to the internal reference code
  • Usage log: who accessed it, when, and for which experiment/project
  • Deviation log: incidents + corrective actions
Pro tip: Use consistent naming and a single archive folder. Example: MAT-2026-01_BATCH14_COA.pdf

Compliance Tips (Safe, Professional)

Compliance is also about how information is presented — clarity, transparency, and avoiding misleading claims.

What is generally safer to say (best practices)

  • Use neutral language: quality, testing method, batch verification, documentation
  • Be transparent: “educational,” “for research processes,” “not medical advice”
  • Avoid promising outcomes or guarantees of results
  • Include a privacy note if you collect data (Canada-friendly language)

What to avoid

  • Therapeutic or medical claims (diagnose, treat, cure, prevent)
  • Before/after or implied body-related outcomes
  • Misleading framing that suggests consumer use
ℹ️
Reminder: Keep public communication consistent with an educational and research-quality framing. If you operate in regulated categories, ensure your wording aligns with platform policies and applicable Canadian requirements.

FAQ

Is this medical advice?

No. This page is educational and informational only and is not intended as medical advice, diagnosis, treatment, or guidance for human use.

Can my team use this page as a reference?

Yes. You can use this page as a general reference for standardizing documentation, COA review, storage logs, and basic QA/QC workflows.

Why are batch and COA checks important?

They support traceability, reproducibility, and more reliable comparisons between experiments by reducing uncertainty about inputs.

What communication style is safer for public pages?

Neutral, educational, and process-focused messaging (quality, testing methods, documentation) while avoiding medical claims or promised outcomes.
