Our technology

Exsolidus® platform

Turns PXRD data into decisions for materials discovery, R&D and manufacturing.

  • A PXRD pattern carries fingerprints of the material, the instrument and the sample preparation.
  • Phase identification, impurity detection, crystallinity, and texture make difference in discovery and production.
  • On laboratory instruments, instrument and sample effects blur these fingerprints. Weak signals, impurities and overlapping peaks are easily missed, and full interpretation often needs scarce expert time or synchrotron beamtime.
  • Exsolidus models remove these aberrations, resolve overlapping peaks and recover weak signals, so analysis is automated and reliable.

Applications

Exsolidus is for

  1. Material characterization

    Exsolidus® Alpha: crystal structure determination

    Automated workflow with minimal user input. Expert support is included for industry partners.

    • Academic users
    You provide
    A PXRD pattern and the molecular formula or SMILES
    You receive
    Refined unit cell, space group, and a structure model, with a full expert report.

    Case study: Automated crystal structure determination of diamantane-4,9-dicarboxylic acid

  2. Production control

    Exsolidus® Detect: impurity detection and quantification

    Identifies and quantifies potential impurities or unwanted forms in APIs and other materials.

    • QC laboratories, including multi-site operations
    • Big Pharma production
    You provide
    Production-sample PXRD patterns measured in your routine mode
    You receive
    Integrated software workflow with impurity detection, identification, quantification and risk profile.

    Case study: Revealing a hidden crystal form in an antibiotic API

  3. High-throughput PXRD screening analysis

    Exsolidus® Screening: Analyze hundreds of diffractograms in bulk

    Comparative and automated analysis of large sets of already-collected diffractograms from screening experiments. Detection of new phases and changes in material properties such as crystallinity and particle size. Determine the structure of new phases and quantify the sample mixtures and get solid forms risk profiles.

    Who uses it

    • Pharma, CDMOs and CROs running solid-form screens
    • Chemical and agrochemical companies
    • AI materials companies and autonomous labs
    You provide
    A set of diffractograms and optionally a reference pattern
    You receive
    List of detected phases with risk profiling

    Case study: Catching a trace polymorph across 12,000 screening patterns

  4. Cement and clinker analysis

    Exsolidus® Cement: quantitative phase analysis

    Identifies the phases in cement or clinker and performs quantitative phase analysis with uncertainty profiles and go/no-go decision implications.

    Who uses it

    • Cement and clinker producers
    • Plant and central quality laboratories
    • Instrument manufacturers serving the cement industry
    You provide
    Cement or clinker patterns from your instrument
    You receive
    Phase identification and weight fractions with uncertainty profiles
  5. Upgrading older PXRD instruments and extending their life cycle 

    Exsolidus® Diffract: reduce instrument and sample aberrations

    Our models reduce instrument and sample aberrations in laboratory PXRD patterns, leaving a corrected pattern with enhanced peak resolution and extracted texture parameters.  This is especially valuable for shorter measurement times. The corrected pattern can be used in your own analysis software or input into other Exsolidus modules. Exsolidus Diffract can be back-installed to any PXRD instrument.  

    Who uses it

    • Laboratories with their own analysis workflows
    • Instrument manufacturers
    • Analysis-software developers
    You provide
    Laboratory PXRD patterns from your instrument and measurement mode
    You receive
    Corrected patterns, ready for your analysis
  6. Patent disputes

    Exsolidus® Patent Examiner: PXRD evidence from patents and papers

    Extracts PXRD data from patents and scientific papers, analyzes it and compares it with your crystal forms, to support your IP team's assessment, and potential patent disputes.

    Who uses it

    • IP and legal teams in pharma
    • Generic and originator manufacturers
    • Patent attorneys working on solid-form patents
    You provide
    Your crystal-form patterns and the patents or papers to check
    You receive
    Extracted patterns and a comparison with your forms, or structural solution confirmation.  
  7. Site-to-site PXRD method transfer

    Understand why method transfer fails

    In development

    When a CDMO or CRO develops a PXRD method that fails at the client's site, a substantial amount of time and money is lost on finding the culprit. Our new methodology tracks both sites and detects whether the cause lies in the instruments, the sample, or the sample processing, so method transfer problems can be traced and fixed quickly.

    Who uses it

    • Multi-site CDMOs and API producers
    • Technology and method transfer teams
    • Big Pharma (as co-development)
    You provide
    Patterns of the same material from several sites or instruments
    You receive
    Diagnostic analysis profiling the potential failure modes and an analytical solution for instrument matching.  
  8. Formulation development

    Exsolidus® Pharma: solid and semi-solid formulation optimization

    In development

    Supports the optimization of solid and semi-solid formulations by tracking the solid forms of the API and excipients across formulation variants. 

    Who uses it

    • Formulation and development teams
    • CDMOs offering formulation development
    • Partners interested in co-development
    You provide
    Formulation under review: form and composition, process conditions and selection criteria, with your formulation data.
    You receive
    Candidate assessment with comparable experimental evidence, predictions at the study conditions and the uncertainties that need a test, and a proposed study plan for scientist approval.
