Support Quality by Design using FT-NIR solutions

Significance of the topic

Near-infrared (NIR) spectroscopy, particularly Fourier-transform NIR (FT-NIR), is a powerful analytical approach for implementing Quality by Design (QbD) in pharmaceutical manufacturing. By enabling rapid, nondestructive identification and quantification of materials at-line, off-line or on-line, FT-NIR supports real-time process monitoring and control, reducing reliance on end-product testing and enabling earlier detection of deviations. This improves batch-to-batch consistency, facilitates regulatory compliance, and shortens development cycles for formulation and process optimization.

Objectives and overview of the application note

The document promotes Thermo Fisher Scientific’s Antaris FT-NIR product family as practical solutions for implementing QbD strategies across the pharmaceutical workflow. Key objectives are to: explain how FT-NIR instrumentation (Antaris II and Antaris MX) can be used for material identification, quantification and process feedback; emphasize reproducibility and calibration transfer across instruments; and position FT-NIR as scalable from laboratory method development to in-line process monitoring. The flyer also situates FT-NIR within a broader laboratory-to-process ecosystem by highlighting complementary analytical tools and workflows for discovery, problem solving and quality assurance.

Methodology

The FT-NIR approach relies on collection of near-infrared spectra and chemometric models for concentration and quality attribute predictions. The workflow elements described include method development, sampling options (transmission, fiber-optic probes, integrating sphere diffuse reflectance), calibration transfer, and real-time communication for process control. Emphasis is placed on robustness of FT-based wavelength precision and instrument ruggedness to maintain stable performance in production environments, supporting both periodic at-line measurements and continuous in-line monitoring.

Used instrumentation

• Thermo Scientific Antaris II FT-NIR: off-line or at-line analyzer for laboratory and production point-of-use measurements; supports multiple sampling modes via the MDS Method Development Sampling System (transmission, fiber-optic, integrating sphere).
• Thermo Scientific Antaris MX FT-NIR: in-line/on-line analyzer for real-time process monitoring and development; features fiber-optic multiplexing and integrated communications for immediate feedback. An ATEX-rated variant is available for hazardous zones.
• Ancillary and complementary instruments mentioned for an integrated workflow: Thermo Scientific DXR2xi Raman Imaging Microscope, Nicolet iS50 and iS5 FTIR spectrometers, HAAKE MARS Rheometer, HAAKE Pharma 11 twin-screw extruder, HAAKE Viscotester IQ rheometer. These instruments illustrate capabilities across chemical imaging, structural and rheological characterization, and process simulation.

Main results and discussion

Although the source material is a product-focused application note rather than an experimental study, several practical conclusions are communicated: FT-NIR instruments with FT wavelength precision provide reproducible spectral data conducive to robust chemometric models and straightforward calibration transfer between instruments; modular sampling configurations enable cross-stage applicability from lab method development to process monitoring; and process-capable instruments with multiplexing and real-time communication enable timely corrective actions during production. The material highlights the strategic advantage of a unified software environment (Result Software Suite) to streamline user training and support consistent method deployment across laboratory and process contexts.

Benefits and practical applications

• Faster decision-making: in-line FT-NIR provides immediate process feedback for control loops and rapid corrective actions.
• Reduced product variability: continuous or frequent monitoring helps detect and prevent deviations early, supporting QbD principles.
• Versatility across stages: a single measurement technology supports formulation development, troubleshooting, and routine QA/QC checks.
• Scalability and reproducibility: FT-based wavelength stability and rugged instrument design aid calibration transfer and consistent performance across environments.
• Regulatory alignment: real-time monitoring and documented, transferable calibrations support process understanding and regulatory expectations for process analytical technology (PAT) and QbD.

Future trends and potential uses

• Increased integration with process control systems: tighter coupling of FT-NIR outputs with distributed control systems and advanced process control algorithms will enable closed-loop pharmaceutical manufacturing.
• Advanced chemometrics and machine learning: deployment of robust multivariate and AI models will improve predictive performance for complex formulations and heterogeneous materials.
• Expanded use in continuous manufacturing: FT-NIR sensors will play a key role in enabling efficient continuous processes such as hot-melt extrusion and continuous granulation.
• Miniaturization and deployment in regulated zones: more compact, intrinsically safe designs will broaden use in constrained or hazardous production areas while maintaining data integrity.
• Harmonized data ecosystems: unified software suites and cloud-enabled data management will facilitate calibration sharing, lifecycle management and regulatory submissions.

Conclusion

FT-NIR, exemplified by the Antaris II and Antaris MX platforms, offers a pragmatic route to embed QbD into pharmaceutical workflows through rapid, non-destructive analysis, reproducible spectral data and scalable deployment from lab to process. When combined with appropriate sampling hardware, robust chemometric models and integrated software, FT-NIR delivers actionable, near-real-time information that enhances process understanding, reduces risk and accelerates development and manufacturing timelines.
