Manufacturing Batch Release

Unknown peaks in chromatograms for the analysis of batch release or stability testing is not unusual. Different compounds can appear for various reasons, such as laboratory contaminations, instrumental- related peaks, leachable and impurities.

RPS provides identification of unknown organic compounds appearing in any kind of chromatogram for Pharmaceutical testing:

  • Impurity profiling
  • Unknown peaks occurring during method development
  • Unknown peaks occurring during API, batch release and stability testing.

Swift identification allows for critical situations to be addressed, avoiding potentially high additional costs and use of resources. This is especially useful in cases where it is not possible to conclude whether the unknown compound is present in the product.

Proper identification of substances coming from contaminations is a precious tool for successful completion of the investigations and implementation of effective CAPAs.

As compliance requirements become tighter, our innovative approach offers the unique opportunity to have a service which is readily available, and where results are provided in five working days. This significantly increases the possibilities for Quality Assurance teams to focus on complicated situations.
