Accurate nanoparticle size distribution analysis is essential for understanding formulation quality, stability, and performance.
Our separation-based approach enables detailed measurement of nanoparticle populations that may not be resolved by ensemble measurement techniques.
Typical analyses include:
• high-resolution nanoparticle size distribution
• detection of large particle impurities
• identification of secondary particle populations
• comparison bvetween formulation batches
Our services
Size Distribution Analysis
Fraction Collection for Downstream Analysis
For complex nanoparticle systems, we work with clients to develop analytical workflows tailored to their formulation and research goals.
This may include optimization of separation conditions, analytical strategies, and data interpretation.
Many nanoparticle systems contain complex particle populations that require separation prior to analysis.
Our analytical workflow enables detailed characterization of heterogeneous nanoparticle formulations, including detection of aggregates and minor particle populations.
Applications include:
• lipid nanoparticle formulations
• polymeric nanoparticle systems
• engineered nanomaterials
• macromolecular complexes
Nanoparticle Characterization Services
Imessa Research provides high-resolution nanoparticle characterization using separation-based analytical methods.
Our services are designed to help researchers and development teams understand the structure, size distribution, and heterogeneity of complex nanoparticle formulations.
We work with academic groups, biotechnology companies, and pharmaceutical developers to provide detailed characterization of nanoparticle systems used in nanomedicine, materials science, and biotechnology
Separation-based analysis allows physical isolation of nanoparticle fractions for further characterization.
Collected fractions can be used for additional analytical techniques or functional studies.
Examples include:
• structural analysis of isolated particle populations
• characterization of aggregates or impurities
• downstream biochemical or materials analysis
