AIR MONITORING


Outdoor-ready ultrafine particle monitor offers real-time data, meteorological insights, and long-term deployment capability


QuantAQ has announced the launch of the MODULAIR-UFP, a new sensor built to measure ultrafine particles (UFPs) in outdoor environments, enabling researchers, regulators, and communities to access new data for air quality monitoring.


Designed to operate outside the lab and in long-term installations, the MODULAIR-UFP measures total particle number concentrations from 0 to 100,000 particles per cubic centimetre (ppm) with minimal maintenance for extended periods.


“Until now, ultrafine particle monitoring has been highly constrained and difficult for long-term outdoor uses,” said David Hagan, CEO and Co-founder of QuantAQ. “The MODULAIR-UFP brings these critical measurements into the field with precision, reliability, and ease.”


Each MODULAIR-UFP is equipped with a Gill® Weather Station, adding detailed meteorological measurements—including wind speed, wind direction, temperature, and humidity—to help contextualise pollution sources. This pairing provides a new level of resolution for understanding local air quality dynamics, particularly in complex urban and industrial environments.


“With its compactness and portability, the MODULAIR-UFP opens


up exciting new research possibilities,” said Dr. Dan Westervelt, Associate Research Professor at Columbia Climate School’s Lamont-Doherty Earth Observatory and QuantAQ customer. “We are particularly looking forward to understanding emissions of ultrafine particles near a major New York City highway as a function of vehicle type, fuel quality, driving conditions, and vehicle age.”


Unlike other UFP solutions on the market, the MODULAIR-UFP uses a water-based, pulsed condensation particle counter (CPC). The sensor is compact, easy to install, and designed for low power consumption. To minimise downtime, the device proactively alerts users when the internal water reservoir is low, allowing maintenance teams to refill while minimizing interruptions to data collection.


The MODULAIR-UFP also connects to the QuantAQ Cloud™ platform, enabling remote, real-time access to high-resolution data across single or multiple sites. Whether for researchers studying near-roadway exposure, city agencies tracking pollution hotspots, or community groups advocating for cleaner air, the MODULAIR-UFP empowers users to monitor UFP levels with flexibility and control.

A full range of gas analysis solutions


New automatic measuring system sets a new benchmark for hydrogen and multigas analysis in the field


As hydrogen assumes an increasingly important role in the global shift to low-carbon energy systems, the need for precise and reliable gas analysis has never been greater. MRU GmbH has launched the MGAprime-H2—a portable, automatic measuring system (P-AMS) that combines advanced analytical features with field-ready convenience.


Designed for industrial and environmental applications where gas quality is crucial — such as hydrogen production, biomethane injection, and process control — the MGAprime-H2 offers the accuracy of a stationary analyser in a durable, portable design. Its key features include MRU’s robust, drift-free NDIR technology, enabling high-resolution multigas analysis with long- term stability, even in challenging environments.

The MGAprime-H2 addresses the complex measurement needs of the energy transition. It provides the accuracy and ease of use required by plant operators and service engineers, emphasising long-term reliability and user-focused automation.


The analyser’s technical capabilities support this mission. Using high-precision NDIR sensors, the MGAprime-H2 can detect up to eight gases at once — including CO, CO₂, CH₄, NOₓ species, SO₂, and N₂O — and also measure oxygen with electrochemical or paramagnetic sensors. Hydrogen detection is achieved through electrochemical technology. These features are essential for combustion optimisation, emission compliance, and fuel- switching scenarios.


Integrated gas conditioning is accomplished by a high-efficiency Peltier gas cooler with dual automatic condensate removal, ensuring sensor protection and sample integrity. The system also includes automatic zero calibration and internal volume flow measurement, further reducing manual intervention and increasing reliability.


User interaction is managed through a large, full-color TFT touchscreen running on a Linux operating system, featuring

intuitive menus and graphical data displays. Output formats include CSV and PDF, enabling integration into QA/QC documentation workflows. Remote operation is achievable via a VNC server over LAN or WLAN, while data transfer is conducted through Ethernet or USB.


Engineered for modern industrial environments, the MGAprime-H2 is housed in a rugged all-metal enclosure with impact-resistant corner protectors and multiple I/O options — including eight analog outputs and four analogue inputs — ensuring compatibility with existing plant control systems.


With complete combustion calculations, programmable measurement intervals, and data logging as standard, the MGAprime-H2 is a comprehensive tool for emission measurement, fuel characterisation, and gas quality verification. From hydrogen infrastructure to waste-to-energy plants, MRU’s latest innovation sets a new standard for portable gas analysis in the era of decarbonisation.
