Parenteral & Combination Drug Products
Unexpected particle counts? Find out what is behind them.
Complement subvisible particle counting with chemical identification and material-specific population analysis to investigate OOT/OOS findings and changes in pharmaceutical components or processes.
USP <788> · Ph. Eur. 2.9.19
Understand your particle counts →
OINDP & MDRS
Comparing formulations? Look beyond particle size alone.
Characterize Raman-confirmed API particles, size distributions and morphology to support test/reference formulation comparisons.
Explore formulation comparability →
Raman identification complements, but does not replace, compendial light obscuration (LO) or microscopic particle-count testing.
Your particle investigation is our starting point.
Every investigation starts with a different question. We listen first — to understand your product, process, previous findings and the decision your team needs to make.
Our specialists combine decades of experience in visible and subvisible particle characterization with proprietary analytical technology and AI-assisted methods.
Together, we define an analytical approach tailored to your samples, whether you need contamination identification, advanced troubleshooting, method development or comparative particle characterization.
Personal communication. Sound analytical judgment. Responsive execution.

More than particle counts. Evidence that helps you investigate.
Identify
Determine the chemical identity of individual particles using Raman spectroscopy.
Quantify
Characterize particle counts, sizes and material-specific populations.
Compare
Examine differences between samples, batches, components and reference formulations.
Investigate
Combine particle characteristics, reference materials and analytical context to support probable-source investigations.
Automated imaging, morphology and AI-assisted classification support the analytical workflow. Material identification and probable-source interpretation depend on suitable measurements, references and investigation context.

From a particle image to chemical identity
A particle image shows appearance. Its measured Raman spectrum provides a chemical fingerprint that can be compared with reference materials. In this original example, particle 11292 was identified as polypropylene. Material identity helps focus the investigation; it does not by itself establish the contamination source.
Particle 11292 · Original particle micrograph and associated measured Raman spectrum from the H01 dataset. Raman identification: polypropylene.
