Certificates of Analysis (COA)

Certificates of Analysis (COA)

Overview

A Certificate of Analysis (COA) is a quality assurance document that confirms a product’s conformity with defined specifications at the time of release. A1prolab provides COAs to qualified buyers as part of our commitment to transparency, traceability, and quality control.

Purpose of a COA

Certificates of Analysis are issued to:

  • Verify compliance with product specifications
  • Support quality assurance and regulatory review
  • Provide batch-level traceability
  • Assist customers in internal quality and audit processes

COAs serve as an official record of analytical results performed on a specific production batch or lot.

COA Content Overview

A typical Certificate of Analysis may include the following information:

  • Product name and identification
  • Batch or lot number
  • Date of analysis and issue date
  • Analytical parameters tested
  • Specification limits and test results
  • Method references (where applicable)
  • Authorized quality control sign-off

The exact content may vary depending on product type and regulatory requirements.

Analytical Testing

Analytical testing referenced in COAs is conducted using recognized laboratory methods appropriate to the product category. Testing may include, where applicable:

  • Purity or concentration verification
  • Physical and chemical property assessment
  • Visual inspection and consistency checks
  • Compliance with internal quality specifications

Testing scope is defined based on product classification and intended application.

Batch Traceability

Each COA is linked to a specific batch or lot, supporting:

  • Product traceability
  • Quality audits and inspections
  • Regulatory documentation requirements
  • Investigation and corrective action processes, if required

Traceability is maintained through structured record-keeping systems.

Availability of COAs

Certificates of Analysis are made available:

  • Upon request to qualified buyers
  • With applicable orders, subject to product and regulatory requirements

COAs are issued only for products and batches where analytical testing has been completed.

Retention & Record Management

COAs and associated quality records are retained in accordance with:

  • Internal quality management procedures
  • Applicable regulatory and documentation retention requirements

This ensures accessibility for audits, inspections, and compliance reviews.

Limitations & Disclaimer

Certificates of Analysis reflect the condition and analytical results of the product at the time of testing only. They do not replace the buyer’s responsibility to:
