How is Investigative Analysis Different from Routine Testing?
Routine testing follows a controlled and predetermined set of protocols with an expectation of results that should either match or not match a defined outcome. This type of compendial testing can generate pages of data, and tell you whether quality control or regulatory specifications have been met.
Data from routine tests can provide information to, for example, verify components of a formulation, or confirm the concentration and purity of ingredients.
What can you do to get answers when your product is out of spec (OOS) due to contaminants, impurities, manufacturing failures, or product defects and routine tests can’t provide a complete understanding of non-conformance?
Our investigative, microanalytical approach may help to provide some answers to your questions when routine testing results or other anaylsis attempts are inconclusive.
Using advanced microanalytical techniques and instrumentation, we apply a detective-style approach to understanding the issues and finding answers at the microscopic level.
We collaboratively work with you to solve non-routine issues such as production contamination and product defects.
Our commitment to quality assurance (cGMP, ISO/IEC 17025:2017 A2LA accredited) ensures you’ll receive reliable, interpreted, peer-reviewed results, and not just a data dump.
When your testing results fall outside of acceptance or tolerance criteria, or exceed preventive controls (OOC), call us to speak to a scientist or submit your analysis request online. We’re here to help you find a solution.
