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: data scientists discovering chemometrics
Synthesised observations from PAT-adjacent engagements where data scientists from web-product backgrounds collide with chemometricians steeped in PLS, ASTM E1655, and calibration transfer.
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: 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.
