Purity & Identity Testing

Assess Your Biologic’s Stability with Purity Testing

Gain lasting confidence in your drug’s composition with identity testing in the form of separation and quantitation – a trusted purity test backed by chromatographic, electrophoretic, and spectroscopic instrumentation. These analytical characterization assessments are valuable for contributing to a larger formulation or process endeavor and acting as a limited troubleshooting tool or feasibility study.

When your project is ready to execute your next purity test, our team of expert researchers are ready to implement identity testing for your biologic.
