Determination of Trace Nitrogen Contents in Different Types of Fuels and Fuel Blends According to ASTM D4629 resp. DIN 51444 v3
Catalyst-free high-temperature combustion and highly sensitive HiPerSens® detection allows the detection of nitrogen at concentrations from 15 µg/l up to 10,000 mg/l.
This interactive e-book celebrates National Forensic Science Week by highlighting the vital role of spectroscopy in modern criminal investigations and emphasizing how technological innovation is making forensic analysis faster, safer, and more reliable for courtroom testimony.
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.
Top content published this week include a feature article on a new innovation called the Personalized Optical Digital Twin (PODT), a recap of the International Conference on Raman Spectroscopy (ICORS) 2026 show, and a Q&A on measuring nanoparticle formation in indoor air.
In the final part of our conversation with Brandon Boor of Purdue University, he explains the respiratory deposition model his team used to analyze indoor particle exposure.
In the second part of our interview with Brandon Boor of Purdue University, he discusses how his team controls experimental variables during cleaning experiments in order to obtain interpretable data.
An upcoming interview with Ji-Xin Cheng, a Theodore Moustakas Distinguished Professor in Photonics and Optoelectronics at Boston University, will highlight his ongoing work in coherent Raman scattering microscopy.
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.
