This interview explores how micro-particle induced X-ray emission and micro-ion beam induced luminescence spectroscopy can analyze trace elements in mummy samples.

Is sample thickness important for signal detection? The answer is yes, and in this interview segment, Thomas Mayerhofer of Leibniz Institute of Photonic Technology explains why.

In this “Pathways in Spectroscopy” episode, Brian Strohmeier, who is Pittcon’s President for the 2027 Conference, talks about his role as Pittcon president, what his main responsibilities are, and the amount of work that is required on his end when planning the 2027 show.

In this interview clip, Thomas Mayerhofer discusses why he re-evaluated the evanescent field in attenuated total reflectance (ATR) spectroscopy.

In this video clip, Jean-Baptiste David, who is a R&D Engineer at CEA-Leti, and Serge Gambarelli, who is a research director at CEA-IRIG and EPR spectroscopy expert, discuss the application areas where electron paramagnetic resonance (EPR) spectrometers could be useful.

What is the evanescent field and how does it relate to attenuated total reflectance (ATR) spectroscopy? Thomas Mayerhofer explains.

Spectroscopy sat down with Jean-Baptiste David, who is a R&D Engineer at CEA-Leti, and Serge Gambarelli, who is a research director at CEA-IRIG and EPR spectroscopy expert, to talk about how EPR spectrometers are changing the way laboratory analysis is conducted.

A competitive job market requires candidates to differentiate themselves in order to secure employment. Hear from experts in the field about the skills spectroscopists need to have to succeed in this ever-changing job market.

Christina Ryder, a postdoctoral researcher at Texas A&M University, discusses the current limitations of using near-infrared (NIR) spectroscopy for collagen prescreening on archaeological bone.

In this Q&A, CEO Don Osborne discusses the design of the EarthDaily Constellation, including its 16-imager-per-satellite architecture, calibration-driven approach, and the broader shift from imagery to reliable measurement at global scale.
