Instrumentation and workflow Volcanic monitoring and environmental research frequently require both gas-phase analysis and direct dissolved-gas measurements in liquids. Hiden Analytical's quadrupole mass spectrometry platforms enable these complementary measurements, with sampling via application-specific interfaces including membrane inlet ...
A recent case study within the Biocycle-UA II program demonstrates how gas-phase mass spectrometry can illuminate depolymerization kinetics during the melt hydrolysis of biopolymers. ...
Electrical measurements and optical emission spectroscopy assessed discharge homogeneity and excited species in the plasma phase.Stable reactive species generated during operation were identified using quadrupole mass spectrometry with a Hiden Analytical HPR-20 system configured in residual gas analyser mode with electron impact ionisation at 70 ...
In field campaigns, portable quadrupole MS provides time-resolved compositional data and rapid feedback, while researchers may combine measurements with site-specific sampling, calibration, and complementary methods depending on objectives and environmental conditions.Why Mass Spectrometry is Used in Volcanic ResearchVolcanic gas composition is a ...
By comparing amorphous and rutile TiO2, the work demonstrates how structural order and electronic properties influence charge transfer and the formation of key reaction intermediates during nitrate conversion.The synergistic effect of illumination and applied potential enables nitrate reduction under mild conditions, with amorphous TiO2 displaying superior activity due to a higher density of ...
This study develops a biodegradable photocatalytic membrane with titanium dioxide (TiO2, p25) nanoparticles with a polylactic acid (PLA) support to remove volatile organic compounds (VOCs) from indoor air. It addresses two challenges simultaneously: (i) achieving effective gas-phase photocatalytic oxidation (PCO) of VOCs and (ii) enabling more sustainable fabrication of photocatalyst ...
In support of next-generation fusion diagnostics, Oak Ridge National Laboratory has evaluated Hiden’s high-resolution quadrupole RGA approach for the ITER Diagnostic Residual Gas Analyser (DRGA), focusing on fast, selective measurement of light species in exhaust streams. The study shows how enhanced-resolution quadrupole operation can deconvolve closely spaced masses—most notably ...
Temperature Programmed Reduction (TPR) with quadrupole mass spectrometry (MS) addresses a long-standing challenge in catalyst characterisation: the inability to distinguish between hydrogen consumption mechanisms during reduction. Conventional temperature programmed reduction reveals when a material responds to hydrogen, but rarely explains how ...
Materials often owe their performance to subtle differences between surface sites, yet these variations are not always easy to distinguish experimentally. As temperature changes, molecules bound to a surface respond in ways that reflect how and where they are attached. Temperature programmed desorption uses controlled heating to trigger such responses in a systematic way. When evolved gas ...
This study rigorously investigated the effect of charge-enhanced dry impregnation (CEDI) method on the physicochemical properties and catalytic performance of a ceria-supported nickel-based catalyst. The primary objective of the CEDI method was to augment the electrostatic adsorption of the nickel precursor onto the ceria support surface during the dry impregnation (DI) process. For a ...
The European Union’s Battery Regulation (EU 2023/1542) marks a new era for energy storage technologies. One of its most significant features is the introduction of the EU Battery Passport — a digital system designed to ensure transparency, sustainability, and traceability throughout the entire battery value chain. From February 2027, every large industrial and electric vehicle (EV) ...
Polystyrene microplastics (PSMPs), small plastic fragments measuring less than 5 µm in diameter, are increasingly recognized as harmful air-borne pollutants. Studies demonstrate their ability to penetrate deep into the lungs, where they can induce oxidative stress, inflammation and airway remodeling. A recent study by Balkrishna et al. (2025) investigates these effects in a murine model and ...
Nanotechnology operates at a scale where a few atoms can change everything. Whether developing next-generation semiconductors, targeted drug delivery systems, or catalytic surfaces, precision is paramount. But how do you ensure consistency, safety, and performance at the ...
Fusion research is the global scientific effort to replicate the energy source of the stars, right here on Earth. It’s a monumental challenge: heating hydrogen isotopes to over 100 million degrees Celsius, confining plasma hotter than the sun, and extracting more energy than the system consumes. Experimental reactors like tokamaks, stellarators, and laser-driven systems are making ...
Conductivity is a defining property in energy materials, influencing everything from battery efficiency to hydrogen fuel performance. Materials with high ionic conductivity enable faster charge transfer and more stable energy storage. Yet, even slight variations in purity, thermal stability, or environmental conditions can alter performance. To address these challenges, researchers turn to ...
