A New Approach to Near- and Mid-Infrared Process Analysis (PDF)

The following articles are the most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during the month of August 2026. Ten articles are individually ranked here by DOI page views.

A history of the James L. Waters Symposium at Pittcon, from its 1987 origins and its founder, instrument entrepreneur James Logan Waters, through thirty-six installments of speakers spanning gas chromatography to generative AI.

Peter R. Griffiths, a pioneering figure in Fourier transform infrared (FT-IR) spectroscopy who authored or coauthored more than 300 scientific papers and numerous books over five decades, died August 29, 2026, at age 84. This tribute traces his career from Oxford and Digilab through Ohio University and the University of Idaho, his landmark books and the Handbook of Vibrational Spectroscopy, and his many honors, including the 2023 Ellis R. Lippincott Award and 2024 Optica Fellowship.

An upcoming talk at SciX 2026 Conference will describe a new multimodal platform using laser ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS) elemental mapping that can detect nanoparticles and microplastics in biological tissue.

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 this “Tutorial Tuesday” clip, we explore one of the spectroscopic techniques that are used to characterize polycyclic aromatic hydrocarbons (PAHs).

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.

The 2026 SciX Conference will offer an assortment of short courses during the conference week in Sparks, Nevada. We highlight these courses below.
