Expanding Academic Collaborations for Air Quality Monitoring: Purdue University and University of Georgia
Comments Off on Expanding Academic Collaborations for Air Quality Monitoring: Purdue University and University of GeorgiaTwo recent collaborations showcase how the AROMA instruments are supporting cutting-edge air quality research, from high-performance buildings to wildland fire simulations.
At Purdue University, Entanglement Technologies partnered with Dr. Nusrat Jung and Dr. Brandon Boor of the Lyles School of Civil and Construction Engineering, who are nationally recognized for their leadership in indoor air quality research. AROMA was deployed alongside advanced instrumentation at the pioneering zEDGE (zero Energy Design Guidance for Engineers) test house. With its real-time, high-sensitivity detection of VOCs, AROMA-VOC played a key role in capturing emissions from various indoor sources, including human activities and volatile chemical product use. This work is part of a broader effort to better understand how processes within buildings influence indoor and outdoor air quality.
At the University of Georgia, Dr. Geoffrey Smith’s lab integrated AROMA into the second phase of the G-WISE (Georgia Wildland Fire Simulation Experiment) campaign, a large-scale collaboration with the U.S. Forest Service, the Pacific Northwest National Lab (PNNL), and several universities. The team used AROMA-VOC to measure BTEX compounds and a range of other VOCs released during controlled burns of representative Southeastern fuel beds. With its rapid response and field-deployable design, AROMA proved well-suited for tracking complex, real-world emissions and advancing the team’s understanding of smoke chemistry and atmospheric impacts.
We are grateful for the opportunity to support these research teams and excited to see how their work continues to shape the future of air quality science.

UK researchers, Entanglement Technologies use new mobile sensors to track pollution
Comments Off on UK researchers, Entanglement Technologies use new mobile sensors to track pollutionThe demand for accurate chemical monitoring sensors is rising globally, as industries continue to grapple with the legacy of manufacturing waste.
New commercial mobile monitoring platforms can be part of the solution to this rising challenge, provided they meet the same high standards as previous monitoring technology. Industry-academic partnerships are making this possible, advancing state-of-the-art detection science.
Globally, more than 5 billion sites exist that are contaminated with legacy industrial wastes and require remediation before they can be reused and/or redeveloped. Despite recent efforts to change manufacturing practices, the legacy of waste contamination and generation persists.
“Chemical wastes are part of our society,” says Kelly G. Pennell, Ph.D., the Earl Parker Robinson Chair Professor of Environment and Sustainability in the UK Stanley and Karen Pigman College of Engineering.
“The idea of zero-waste is both an aspirational goal and an elusive goal,” said Pennell. “We know that manufacturing ecosystems are being rapidly disrupted. As a result, there will be unintended, unimagined and uneven consequences of industrial waste that impact the health and environment in communities in various geographic locations.”
That’s why Pennell’s team at the University of Kentucky Superfund Research Center, which was funded by the National Institute of Environmental Health Sciences, collaborated with Entanglement Technologies, located in the San Francisco Bay Area, over the past decade to create meaningful solutions to the chemical waste challenge.
Systematic Quality Assurance/Quality Control Framework for a Volatile Organic Compound Real-Time Monitoring Instrument, Autonomous Rugged Optical Multigas Analyzer for VOCs
Comments Off on Systematic Quality Assurance/Quality Control Framework for a Volatile Organic Compound Real-Time Monitoring Instrument, Autonomous Rugged Optical Multigas Analyzer for VOCsWorking with collaborators at the University of Kentucky, Entanglement Technologies has demonstrated a quality assurance/quality control framework for AROMA-VOC. The results, published in the journal ACS Omega, are important in validating new technologies for environmental monitoring. Check out the abstract here, and then the full article.
Abstract
This study presents a systematic quality assurance/quality control (QA/QC) framework for new technology adopters to validate environmental monitoring instruments when consistent, standardized validation and calibration procedures do not readily exist. This QA/QC framework is especially relevant for newly developed environmental monitoring instruments prior to deployment in field settings as part of environmental site investigations. Key QA/QC parameters used in the framework include repeatability, intermediate precision, reproducibility, linearity, limits of detection (LOD), limit of quantification (LOQ), trueness, and recovery. The QA/QC framework is demonstrated on the autonomous rugged optical multigas analyzer for VOCs (AROMA-VOC), a technology that employs cavity ring-down spectroscopy (CRDS) with preconcentration and chromatographic separation prior to CRDS detection. QA/QC protocols for nine VOCs, and results for AROMA-VOC were compared with laboratory-based gas chromatography/mass spectrometer (GC–MS). Results demonstrated high linearity (R2 > 0.95) and low LOQ values (0.0004 ± 0.0002–0.0455 ± 0.0192 μg/L). The instrument also exhibited ranges of LOD at least an order of magnitude lower than that of the referenced GC–MS. AROMA-VOC demonstrated acceptable precision [repeatability, intraday relative standard deviation (RSD %): 1.72–12.1%; intermediate, interday RSD %: 2.01–10.93%] and substantial recovery (104.8% to 212.4%). Interlaboratory testing also concluded that AROMA-VOC can produce consistent detections (R2 > 0.90). The z-score findings suggested that the performance of the instrument was satisfactory, with the exceptions of xylenes and 1,3-butadiene. Overall, using the systematic QA/QC framework presented in this study, AROMA-VOC is shown to be a robust method for volatile organic compound analysis.
