Elemental Impurities

Elemental impurities testing is essential for detecting trace metals in pharmaceutical products and ensuring compliance with ICH Q3D guidelines. These impurities can originate from raw materials, manufacturing equipment, or packaging systems and must be carefully controlled to protect product safety and quality.

What Is Elemental Impurities Testing?

Elemental impurities testing is used to detect and quantify trace metals in pharmaceutical products, raw materials, and drug substances. Elemental impurities can originate from catalysts, manufacturing equipment, water sources, or packaging materials. These impurities must be controlled to ensure product safety and regulatory compliance.

Regulatory frameworks such as ICH Q3D and USP <232>/<233> define strict limits for elemental impurities in drug products. Testing ensures that these limits are met throughout development and production.

Why Elemental Impurities Testing Matters

Elemental impurities can impact patient safety and product stability. Even trace levels of toxic metals such as lead, arsenic, cadmium, and mercury must be carefully monitored.

This testing is critical for:

  • Regulatory compliance with ICH Q3D and USP standards
  • Risk assessment of raw materials and manufacturing processes
  • Ensuring drug safety and quality
  • Supporting global regulatory submissions

We offer GMP-compliant elemental impurities analysis of pharmaceutical products, ingredients, active pharmaceutical ingredients (APIs), and other health products. Our facilities have some of the most sensitive tools available, and our metals analysis experts have decades of experience. Typical limits of quantification are much lower than typical PDE requirements, with some reaching ppt (parts per trillion) levels with as little as 10 mg of sample weight. Our facilities offer a full range of services, from initial scans to help with pre-risk assessment to full and thorough ICH method validation. Because we have a lot of experience, we can manage each product and project in an open way that involves everyone.

We make sure that elemental impurities in small and large molecule drug products are under control by having a deep understanding of regulatory requirements, a consultative approach, a well-equipped lab, and a track record of finding the best methods for complex and difficult samples. Our end-to-end solutions include regulatory-driven elemental impurities risk assessment support, screening, batch-to-batch testing, raw material testing, method development, validation, and optimization, and elemental impurities USP 232/233 and FDA ICH Q3D testing programs.
