Surface Science Services
(say that three times fast)
From particle size analysis to flow characterization, our analytical laboratory provides you with complete
analysis and reports tailored to your needs. Triclinic Labs offers complete Powder Characterization Services
on certified and calibrated equipment to assist you in characterizing your materials. We utilize surface
science to assess surface, physical and chemical properties as well as develop strategies for formulation with
emphasis on dry powder functionality either for oral or inhaler dosage forms. We have experience with tablets,
hard and soft gelatin capsules, solid dispersions, and self-emulsifying systems. We specialize in analysis of
physico-chemical properties of powders and interactions among powders (agglomeration and segregation) as well
as surface properties as they relate to functionality of drugs and excipients.
Our characterization services allow you to:
- Investigate particle-particle interactions and interactions of water vapor with different surfaces
- Understanding agglomeration and flow of particles
- Understanding adhesion of particles to processing equipment, substrates
- Quantify the effects of surface variability on product’s functionality in order to establish meaningful criterion for acceptance
- Access stability during formulation processing and storage
Understand Processes and Particle Phenomena induced by
- Milling
- Fracture & Disorder
- Drying
- Hot Melt Extrusion
- Spray-drying
- Powder Flow
- Segregation and Agglomeration
- Stability and Performance
- Solubilization and Dispersability

Ask us about:
- Blending and milling analysis using novel technologies (IGC, AFM, SEM, Confocal microscopy, DMA, vapor sorption, XPS and spectroscopy).
- Inline Sensor (NIR and Raman) usage in PAT approaches for assessing blend homogeneity and sameness of milled materials.
- Using quality-by-design for controlling materials, formulation, and processes to comply with the FDA PAT initiative.
Figure 1. A batch of an active pharmaceutical ingredient before and after milling that passed all required physicochemical tests according to specifications but did not flow like other batches in the mill (i.e. it completely clogged the mill). We can utilize particle characterization to determine how early we can anticipate deviations from desired powder behavior upon milling, and avoid them.
