What is process analytical technology (PAT)?
A primer on PAT — the FDA-driven framework for measuring chemistry where it happens, why pharmaceutical and chemical manufacturers adopt it, and the tools that make it practical.

Raman vs NIR for inline chemistry: a decision framework
Both techniques measure chemical composition without sampling. The choice is rarely close once you map your process onto five questions: water, fluorescence, specificity, dynamic range, and probe access.
Chemometrics 101: the math that turns spectra into decisions
Spectra are not answers. The bridge between a 1,000-channel spectrum and a number you can act on is chemometrics — a small toolbox of multivariate methods, used the same way for forty years.
