What Are Extractables and Leachables in Biopharma?
Extractables and Leachables in Biopharma are chemical substances that may migrate from contact materials into biologic drug products.
Extractables are compounds released under forced laboratory conditions such as high temperature or solvent exposure.
Leachables, on the other hand, are compounds that migrate under normal storage or usage conditions.
These substances may originate from container closures, filters, or manufacturing systems, potentially affecting drug purity and safety. Comprehensive E&L studies help manufacturers identify these compounds early, reducing patient risk and ensuring global regulatory compliance.

Regulatory Framework for E&L in Biopharma
Global health authorities such as the FDA, EMA, and USP highlight the importance of evaluating Extractables and Leachables in Biopharma to guarantee patient safety and product reliability.
| Regulatory Body | Reference Guideline | Key Focus |
|---|---|---|
| FDA | FDA E&L Guidance | Risk-based evaluation for biologics |
| USP | USP <1663> & <1664> | Assessment of extractables and leachables |
| ISO | ISO 10993-18 | Chemical characterization of materials |
At ResolveMass Laboratories Inc., our testing follows these global standards for accuracy and consistency. Our E&L Testing for Regulatory Submission process ensures that all biologic products meet FDA and EMA expectations. We also assist with CMC documentation, report generation, and regulatory filing support, ensuring complete data integrity from start to finish.
Analytical Workflow: How Extractables and Leachables Testing Works
The testing process for Extractables and Leachables in Biopharma follows a detailed, step-by-step methodology to ensure precision and reliability:
- Controlled Extractables Study – Performed under stress conditions to identify potential compounds (Learn More).
- Leachables Simulation – Replicates real storage and usage environments to observe actual migration.
- Analytical Screening – Uses advanced tools such as LC-MS, GC-MS, and ICP-MS (Analytical Techniques).
- Toxicological Risk Assessment – Evaluates compounds against safety thresholds like the Analytical Evaluation Threshold (AET).
- Regulatory Reporting – Prepares validated reports for submission to FDA or EMA authorities.
Each step ensures that results are traceable, validated, and compliant with international regulatory expectations.
Key Analytical Techniques for E&L in Biopharma
ResolveMass Laboratories employs state-of-the-art analytical instruments to identify and quantify extractables and leachables with the highest precision:
- GC-MS: Detects volatile and semi-volatile organic compounds.
- LC-MS/MS: Targets polar and non-volatile extractables.
- ICP-MS: Identifies trace metals and inorganic leachables.
- FTIR & NMR: Provide structural details of unknown compounds.
Our Fast E&L Testing Services ensure accurate and reproducible results under cGMP guidelines. This high level of analytical sensitivity supports rapid risk evaluation, helping clients meet regulatory deadlines efficiently.
Extractables vs. Leachables: Key Differences
| Parameter | Extractables | Leachables |
|---|---|---|
| Test Conditions | Accelerated (forced) | Real-time storage |
| Purpose | Identify all potential risks | Evaluate actual exposure |
| Detection | Solvent-based extraction | Product-based migration |
| Regulatory Use | Risk identification | Safety confirmation |
Understanding these differences allows biopharma companies to design comprehensive testing programs. Extractables testing predicts potential issues, while leachables testing confirms product safety under real-world use conditions.

FAQs on Extractables and Leachables in Biopharma
Extractables and leachables are chemical substances that can migrate from packaging materials, tubing, or manufacturing systems into biologic drug formulations. Extractables are identified under forced conditions like heat or solvents, while leachables occur naturally under normal storage and usage. Detecting and controlling these compounds ensures drug purity, safety, and regulatory compliance.
E&L testing is essential because biologics are sensitive to even trace levels of chemical contaminants. These impurities can cause protein instability, reduce drug effectiveness, or trigger immune reactions in patients. Comprehensive E&L studies help manufacturers ensure product consistency and safeguard patient health throughout the product’s lifecycle.
Global authorities such as the FDA, USP, EMA, and ISO have developed specific guidelines for Extractables and Leachables in Biopharma. Key documents include USP <1663> and <1664>, ISO 10993-18, and FDA E&L guidance. Following these standards ensures that every biologic product meets international quality and safety expectations during approval and post-market use.
The Analytical Evaluation Threshold, or AET, is the minimum concentration level at which any compound found during testing must be assessed for toxicological risk. Establishing an accurate AET ensures that all potential impurities are reviewed for safety relevance. It serves as a critical benchmark in determining whether compounds may impact product quality or patient safety.
ResolveMass Laboratories strictly follows globally recognized standards such as USP, ISO, and FDA guidance for E&L testing. Every study is conducted using validated methods under cGMP conditions, ensuring consistency and traceability. Our regulatory experts also assist clients in preparing CMC documentation and submission-ready reports that meet global agency expectations.
