Extractables and Leachables

Pine Lake Laboratories is the scientific leader in extractables and leachables (E&L) studies. We have extensive experience with a wide variety of pharmaceutical container closures systems, single use system components, and combination devices.
Our extraction studies are designed following the original PQRI guidance's and have evolved to include USP <1663> and <1664>. We can perform a material risk assessment at the beginning of the study to assure proper extraction study design and full compliance with the latest regulations.

Our experienced scientific staff utilizes the following analytical methods for expert identification of extractables observed in a forced extraction study:
  • Headspace GC-MS for identification of volatile organic extractables
  • GC-MS for identification of semi-volatile organic extractables
  • LC-QToF for identification of non-volatile organic extractables
  • ICP-MS for identification of inorganic extractables

Pine Lake Laboratories has a proven track record in developing and validating methods used to insure the quality of combination devices, especially combination pharmaceutical medical devices. Our experience allows us to adapt validation strategies and assist in testing designs to meet the unique challenges of combination devices.
