This Tuesday afternoon session will honor Paul A. Wilks Jr., an expert in infrared spectroscopy, former member of Spectroscopy's Editorial Advisory Board, and founder of five different companies throughout the course of his life. The session will also address recent developments in infrared spectroscopy and its future as a technique.
This Tuesday afternoon session will honor Paul A. Wilks Jr., an expert in infrared spectroscopy, former member of Spectroscopy's Editorial Advisory Board, and founder of five different companies throughout the course of his life. The session will also address recent developments in infrared spectroscopy and its future as a technique.
The first presentation in this session will honor Wilks and his many accomplishments, including his company Wilks Scientific. Anthony Gilby, retiree from Waters Corporation, will present historical material honoring Wilks’ legacy in his talk “The Wilks Scientific Years – How Does a Small Company Find and Hit the Jackpot?”
Following Gilby’s presentation will be “Does FT-IR Have a Future?” given by Peter Griffiths of the University of Idaho. Griffiths will offer predictions on the future of hand-held IR instruments. In the final part of this talk, Griffiths will address the question of whether infrared spectrometers be made even smaller through the application of quantum cascade lasers.
Next will be a presentation from Andre Sommer of the University of Miami, “Evanescent Wave Imaging:From Large Unconvetional Samples to Single Cells.” This presentation will focus on the major developments in ATR spectroscopy since the 1960’s and highlight some of Wilks’ innovations in the method.
“Why Infrared Expertise Matters in Today’s Turnkey World,” is the next presentation and will be given by Gloria Story of P&G. Story will share a real-life story, in honor of Wilks, that lends support to the idea that providing training in the fundamentals of infrared spectroscopy should be a part of every analytical chemistry educational program.
The final presentation of this session will be given by Christopher D. Brown of Ahura Scientific and is titled “Design and practical applications for full-capability pocket FTIRs.” Brown will discuss handheld FT mid-infrared (FTIR) spectrometers and illustrate facets of this portability paradox through topics in device design, and some examination of applications in food and industrial processing, and safety/security.
AI and Dual-Sensor Spectroscopy Supercharge Antibiotic Fermentation
June 30th 2025Researchers from Chinese universities have developed an AI-powered platform that combines near-infrared (NIR) and Raman spectroscopy for real-time monitoring and control of antibiotic production, boosting efficiency by over 30%.
Toward a Generalizable Model of Diffuse Reflectance in Particulate Systems
June 30th 2025This tutorial examines the modeling of diffuse reflectance (DR) in complex particulate samples, such as powders and granular solids. Traditional theoretical frameworks like empirical absorbance, Kubelka-Munk, radiative transfer theory (RTT), and the Hapke model are presented in standard and matrix notation where applicable. Their advantages and limitations are highlighted, particularly for heterogeneous particle size distributions and real-world variations in the optical properties of particulate samples. Hybrid and emerging computational strategies, including Monte Carlo methods, full-wave numerical solvers, and machine learning (ML) models, are evaluated for their potential to produce more generalizable prediction models.
