Chemometrics and Artificial Intelligence
Models that turn spectra and sensor data into decisions you can trust.
Chemometrics applies multivariate statistical methods to analytical and process data, enabling complex measurements to be transformed into actionable, decision-relevant information. It remains the primary engine for this purpose, with AI and machine-learning methods becoming increasingly relevant for multiple use cases.
We prioritise approaches and governance frameworks that promote technical robustness, explainability, and regulatory acceptability, so models can be trusted in routine manufacturing, not just explored in research or development settings.
Chemometric and AI models are often poorly governed, limiting trust and regulatory acceptance
Multivariate and AI models lack clear intended use and governance
Risk of “black box” solutions that are hard to explain and defend
Weak linkage between models and CQAs, CPPs and control strategy
Inconsistent lifecycle management of models and data
Regulatory expectations on explainability and oversight are increasing
Why Chemometrics and AI matter
Define clear intended use and model scope aligned with process needs
Develop transparent, explainable chemometric and AI models
Integrate models into PAT, QbD and validation frameworks
Establish robust model lifecycle management and monitoring
Ensure compliance with evolving regulatory expectations
What we do under Chemometrics and Artificial Intelligence
We help you frame, design, and operate models as part of a coherent PAT and quality framework, rather than as isolated data-science experiments. Our focus is on chemometric, and AI models used within PAT to support monitoring, control, and decision-making in regulated manufacturing, with an emphasis on robustness, explainability, and lifecycle management so models can be trusted in routine use.

Define target outputs and required throughput
Classify intended use: monitoring, decision support, real-time control, release or trend-based CPV
Assess risk and criticality in line with PAT, process-model and AI-governance regulatory expectations
Assess how human review and override will work, especially for higher-risk use cases
This anchors model design and validation in a clear regulatory and business context, and sets realistic expectations for what chemometrics, and where applicable, AI should deliver.

Assessing the inventory of existing data sources (PAT tools, historians, MES, LIMS, batch records) and assess their suitability for chemometric and multivariate modelling
Designing data-collection campaigns where gaps exist, often linked to DoE, QbD or validation activities
Defining sensible pre-processing steps
Supporting you in enabling basic data-governance controls in place, aligned with your data-integrity policies
The aim is to create curated, versioned data sets that can support development, validation and future re-training.

Multivariate calibration and prediction – chemometric methods such as PLS and PCA-based approaches for spectroscopy and multi-sensor systems, turning complex signals into quantitative estimates of CQAs or CPPs.
Classification and anomaly detection – supervised and unsupervised multivariate models to flag abnormal batches, drifts and sensor faults before they become deviations.
Soft sensors and virtual analysers – models that infer hard-to-measure CQAs from easier signals or secondary measurements, supporting RTRT and CPV where appropriate.
These approaches enable PAT models that support timely and informed process decisions and can be sustained within routine manufacturing operations.

Defining acceptance criteria that link directly to process performance, product quality, and business impact
Verifying model performance using independent data sets representative of both normal operations and edge-case conditions
Analysing uncertainty, sensitivity and robustness to process changes and instrument drift
Documenting methods and results in a way that fits your validation and QMS framework
Together, these activities provide documented evidence that models are fit for their intended use and can be reliably applied, governed, and maintained within routine operations.

Supporting integration of models into PAT platforms or decision support tools
Establishing monitoring for performance and drift, including triggers for investigation, re-calibration or retirement
Defining practical governance; ownership, versioning, change control, audit trails and documentation expectations
Providing training for data, QA, manufacturing and quality-engineering teams so everyone understands the model’s limits.
This ensures models remain controlled, understood, and effective throughout their lifecycle, supporting reliable decision-making in routine manufacturing.
Deliverables
Depending on scope, typical deliverables include:
Clear description of intended use, decisions, and risk classification.
Data inventory, quality considerations, and pre-processing steps with traceability.
Definition of model structures, training approaches, and feature sets with rational.
Risk-based validation approach aligned with FDA and ICH guidance.
High-level integration, monitoring, and lifecycle management strategies.
User guidance and training for QA, manufacturing, and technical teams.
