Quadrupole and membrane-inlet mass spectrometers sit between gas chromatography and inline spectroscopy in the PAT toolkit. The placement and the limits of the technique are settled, even if vendor marketing is loose.
Recent literature on SERS substrates points at flexible cellulose, 3D-printed metals, and uniformity-engineered nanostructures. We review what is useful for industrial work and what stays in the lab.
Synthesised observations from PAT-adjacent engagements where data scientists from web-product backgrounds collide with chemometricians steeped in PLS, ASTM E1655, and calibration transfer.
Recap of process analytical talks, awards and sessions from PITTCON 2026 in San Antonio and the analytica conference 2026 in Munich, with verified program details from both organizers.
Focused beam reflectance probes return a chord-length distribution, not a particle-size distribution. The difference is what determines whether the signal is useful in crystallization and slurry monitoring.
March-May 2026 in ACS Analytical Chemistry: three threads for process analytics - close-focus Raman probes for turbid streams, deep-learning chemometrics, and open-source spectroscopy tooling.
SERS makes Raman a billion times stronger and a hundred times more fragile. For most inline measurements that is the wrong trade. The places where it pays off are narrow but real.
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.
Six recent reviews map where hyperspectral imaging now sits as a process-analytics tool in pharma, food, recycling, and beyond - and where chemometrics, data hunger, and standards still hold it back.
