LC–MS system
The Orbitrap Fusion Tribrid LC–MS system from Thermo Fisher Scientific combines quadrupole, Orbitrap, and linear ion-trap mass analyzers and is designed for the analysis of complex biological samples. According to the company, users can choose between fragmentation modes at any stage of MSn analysis and unknowns in small-molecule experiments can be identified conclusively as they are encountered.

PEEK fittings
Cheminert high-pressure PEEK fittings from VICI Valco are rated at 5000 psi with fingertight nuts. According to the company, the fitting designs permit direct connection of 360-μm o.d. fused-silica, PEEK, stainless steel, or electroformed nickel tubing without having to use liners.

Mass spectrometer
The LCMS-8040 triple-quadrupole mass spectrometer from Shimadzu is designed to provide polarity switching at 15 ms and a high speed-scanning rate of 15,000 u/s. According to the company, the instrument's UFsweeper II collision cell design enables MRM transition speeds of up to 5555 MRM/s.

Portable GC–MS system
The Tridion-9 portable GC–toroidal mass spectrometry system from Torion is designed for field GC–MS applications. The system reportedly combines an electronic pressure controlled gas chromatograph with an amplitude scanning toroidal ion-trap mass spectrometer. According to the company, the system can be used with SPME syringes for sample introduction.

The bulky bench-top NIR spectrometer is quietly being dismantled and rebuilt as a wafer-scale photonic chip, a self-calibrating algorithm, and a sensor small enough to ride in a shirt pocket. What once demanded a grating, a moving mirror, and a climate-controlled lab now fits inside a handheld module, a bioreactor probe, or a drone payload, and it increasingly figures out what it is looking at on its own.
In the first part of a multi-part Q&A, Brandon Boor, the Dr. Margery E. Hoffman Associate Professor in the Lyles School of Civil and Construction Engineering at Purdue University, describes the instrumentation and methodology behind measuring nanoparticle size distributions at the nanocluster scale (1–3 nm) and outlines the technical challenges of acquiring reliable, real-time data at these dimensions.
Reliability, dynamic measurements, artificial intelligence, and real-world applications are reshaping Raman spectroscopy – while Molecular Photonics points toward new translational frontiers.
In this “Tutorial Tuesday” clip, we explore one of the spectroscopic techniques that are used to characterize polycyclic aromatic hydrocarbons (PAHs).
An upcoming presentation will explore how we can better understand and control nanoparticle morphology is critical for tuning material performance.
Jurgen Popp, Thomas Mayerhofer, and colleagues at Leibniz IPHT and Friedrich Schiller University Jena introduce the Personalized Optical Digital Twin (PODT), a Photonics21 contribution to Europe's Virtual Human Twin ecosystem that connects molecular photonics—Raman blood analysis, coherent Raman tissue imaging, and multimodal endomicroscopy—with longitudinal physiology and clinical data. Drawing on the published multicenter INTELLIGENCE trials, the authors argue that technical feasibility and clinical utility must be evaluated separately as the field moves toward Europe's FP10 research agenda.
