CMAC National Facility - X-Ray Diffraction and Solid-State Characterisation

Definitive structural insight to de-risk development

For pharmaceutical developers and materials researchers, unanswered solid-state questions create risk - slowing decisions, complicating formulations and undermining regulatory confidence.

Our integrated hub enables you to de-risk solid form selection early in development to:

  • Make faster, evidence-based decisions on polymorphs, salts and phases

  • Strengthen regulatory submissions with structural justification

  • Progress development when single crystals are unavailable

  • Avoid late-stage reformulation and stability surprises.

We focus on outcomes - not just measurements to ensure data translates into decisions.

What sets us apart

Structure solution from powder data - a rare capability

Structure determination from powder X‑Ray diffraction data is a highly specialised capability, available at only a small number of facilities worldwide.

At CMAC, we routinely solve structures directly from powder data, supporting development programmes where single‑crystal material cannot be obtained or where timelines don’t allow repeated crystallisation attempts.

This allows you to:

  • Resolve ambiguous solid forms with confidence

  • Support patent, IP and regulatory arguments

  • Advance development without dependency on crystal growth

  • Reduce uncertainty in solid‑state risk assessments

This capability is particularly valuable in early‑stage pharmaceutical development, where material is limited and decisions are time‑critical.

  • A complete solid-state landscape in one place

    Our integrated analytical and experimental environment allows us to map the entire solid‑state landscape, from single crystals to amorphous materials.

  • Expert-led, problem‑focused studies

    Our crystallographers and solid‑state specialists deliver studies that connect structure, stability, transitions and microstructure to product performance.

Core capabilities:

  • Identify what’s in your sample, and how much.

    Powder X-Ray diffraction is the gold standard for determining crystalline phases in complex materials. By matching diffraction patterns against extensive reference databases, we rapidly identify the phases present and quantify their relative proportions.

    These capabilities support troubleshooting manufacturing issues, monitoring crystallisation outcomes, verifying product consistency and analysing unknown materials.

  • Understand how your materials respond to real-world conditions.

    Using controlled temperature and humidity diffraction experiments, we monitor structural transformations including polymorphic transitions, hydrate formation, desolvation and thermal phase changes.

    These measurements provide critical insight into material stability under realistic storage and processing conditions, supporting form stability assessment, identifying transformation pathways and informing formulation and manufacturing strategies.

  • Get complete crystal structures - even without crystals.

    We provide full three-dimensional structure determination using state-of-the-art single-crystal and powder X-Ray diffraction. When suitable single crystals cannot be obtained, advanced computational methods allow us to solve structures directly from high-quality powder data.

    This capability spans small molecules, salts, cocrystals, solvates, hydrates and complex multi-component systems. Structural insight enables confident polymorph identification, understanding of hydrogen-bonding networks and molecular packing, and interpretation of physicochemical properties, supporting pharmaceutical development, materials research and regulatory documentation.

  • Visualise internal structure without sample preparation.

    X-Ray microscopy and computed tomography provide non-destructive 3D imaging at micron-scale resolution, revealing pores, inclusions, cracks and phase distributions all without altering your sample.

    This technique offers insight into particle morphology, internal architecture and structural heterogeneity across pharmaceutical, advanced materials and device applications. Combined with diffraction-based methods, it links 3D microstructure to crystallographic and compositional data to give you a full picture of your material from the inside out.

  • Explore structural behaviour under extreme conditions.

    High-pressure X-Ray diffraction reveals how materials respond to compression, uncovering new polymorphs, phase transitions and pressure-driven structural changes that remain hidden at ambient conditions.

    Using diamond anvil cells and other specialised equipment, we access regions of the solid-form landscape that offer unique insight into intermolecular interactions, packing efficiency and structural stability. This capability is particularly valuable for fundamental research and advanced solid-state investigations.
