Elemental impurities testing is a method of qualitatively and quantitatively analyzing packaging components, raw materials, and products for potentially toxic elements. In 2018, Elemental impurities testing became an FDA and Health Canada regulatory requirement. As a result, the pharmaceutical manufacturing industry must comply with these requirements and CPL is fully equipped to do just that. At CPL, our expert team of chemists will utilize state-of-the-art equipment to analyze your samples and provide cGMP documentation to support and present the data.


CPL will help to:

  • Support your project from inception to completion
  • Understand and manage the challenges from USP <233> and <232>, EP, and ICH Q3D
  • Conduct a Risk Assessment based on your excipients, API, packaging components and manufacturing equipment to support regulatory applications
  • Determine if quantitative or qualitative testing is required
  • Utilize a customized approach to screen elemental impurities
  • Establish limits in drug products to adhere to regulatory USP and EP requirements

CPL provides:

  • Experience in method development, validation, transfer, and routine testing for elemental impurities in packaging components, raw materials, excipients, APIs, and drug products
  • Verification of Pharmacopeial methods
  • Study transfer from different analytical technologies to ICP-MS (from ICP-OES or AAS)
  • Experience with a variety of different sample types and complex sample matrices including, oral, parenteral, inhalation, and topical products
  • Investigative analysis – an element might be linked to a product failure i.e., amalgamation or identification of metal particles
  • Evaluation of leachable-extractable profiles on both manufacturing and packaging contact materials to support USP <1663>, <1664>, <661.1> and <661.2> requirements
  • Determination of trace metals in water and waste by EPA (Environmental Protection Agency)
  • Product reverse engineering support
  • Closed vessel microwave digestion
  • Hydrofluoric Acid testing capabilities
