Field notes: commissioning inline Raman on a new production line
A composite of patterns from inline Raman commissioning projects on new-build lines. The physics rarely delays the go-live; the sample point, the ATEX file, and the calibration set do.

Field notes: getting inline analytics onto surfactant ethoxylation lines
Ethoxylation reactors are batch, hot, pressurised, flammable. Raman fits the chemistry cleanly, but field work is dominated by ATEX, safety, and reactor-cycle integration - not the spectroscopy.
Field notes: regulatory inspectors and PAT
A composite of practitioner conversations on FDA and EU inspections that put process analytical technology and chemometric models in scope. Inspectors read the lifecycle records, not the qualification protocols.
Field notes: validation engineers and the PAT lifecycle
A composite of conversations with validation engineers working on pharmaceutical and biopharmaceutical PAT installations. The hardest parts of the job sit at the seams between project, quality, and operations.
Field notes: small vendors and the analytics supply chain
A composite from mid-market plants in Central and Eastern Europe on what it means to buy process analytics from a vendor that is not Thermo, Agilent, or Mettler. The list is longer than the catalogue.
Field notes: what scaling PAT across multiple plants actually involves
A composite of conversations with engineers running multi-site PAT programs. The technical work is straightforward; the parts that go wrong are organizational, contractual, and cultural.
Field notes: why chemometricians and process engineers talk past each other
A composite of observations from PAT projects where the model team and the line team had everything they needed except a shared vocabulary. What both sides actually mean by the words they use.
Field notes: pharma and chemicals run PAT in different cultures
A composite of observations from practitioners who have worked PAT projects on both pharmaceutical and bulk-chemicals sites. The instrument is often the same; almost everything around it is different.
