Certificate of Analysis testing is the laboratory process that verifies whether a product or raw material meets specified quality standards for identity, potency, purity, and safety. The result of this testing is a COA (Certificate of Analysis)—a formal document used in quality control, regulatory compliance, and product approval processes.

At Qalitex, we specialize in COA testing for dietary supplements, cosmetics, personal care products, and chemicals, providing fully documented reports accepted by Amazon, the FDA, and international regulatory bodies.

Why Certificate of Analysis Testing Matters

COA testing is essential for:

• Regulatory Compliance – Including FDA, GMP, EPA, EU, and REACH

• Amazon Seller Requirements – Prevent listing removals with compliant COAs

• Label Accuracy – Confirm that active ingredients match stated claims

• Quality Assurance – Identify contamination, adulteration, or potency loss

• Buyer Confidence – COAs are used in B2B and private-label sales as a trust document

A properly issued Certificate of Analysis builds transparency, reduces recalls, and protects your brand reputation.

What’s Included in Our COA Testing Panels

Every Certificate of Analysis is customized to your product type. Common testing parameters include:

1. Identity Testing

Confirms the material is what it claims to be (via HPTLC, FTIR, or DNA).

2. Potency Testing

Verifies active ingredient levels (using HPLC, GC-MS, or UV-VIS methods).

3. Purity & Contaminants

Checks for heavy metals (ICP-MS), residual solvents, pesticides, or adulterants.

4. Microbial Testing

Measures Total Plate Count (TPC), yeast and mold, and pathogenic bacteria such as E. coli or Salmonella.

5. Physical Properties

Includes pH, viscosity, moisture content, and appearance, where applicable.

Your COA will include these results, along with pass/fail evaluations and complete method traceability.
