We are expanding our market presence in Europe. Previously, in April 2022, DCMR Rijnmond Environmental Service used AROMA-VOC for air quality monitoring of benzene, toluene, ethylbenzene, and xylene(s) (BTEX) emissions at the Port of Rotterdam in the Netherlands. Now, AROMA-VOC is undergoing an independent instrument evaluation with AQUILA, the Air Quality Unit of the European Commission’s Joint Research Center, in Ispra, Italy. Sponsored by DCMR, the study will evaluate instrument accuracy, stability, and robustness to common atmospheric interferents.
AROMA-VOC provides real-time part-per-trillion chemical detection in ambient air and other complex, real-world sampling environments. The analyzer is particularly well-suited to air quality measurements where mobility and long-term stand-alone operation provide significant advantages over traditional sampling methodologies. AROMA-VOC provides a much faster response than low-resolution GC instruments while providing the sensitivity and selectivity of laboratory multi-column GC-MS systems. The AROMA family of instruments all share a simple interface that can be accessed from anywhere and that provides long-term autonomous intervention. The intrinsic stability of the cavity ring-down spectroscopy (CRDS) analyzer core minimizes maintenance and calibration requirements greatly reducing instrument operation overhead. Contact us today to learn more about how AROMA-VOC can enhance your ambient air monitoring capabilities.
We are exhibiting at the National Ambient Air Measurements Conference from August 23rd to August 25th at the David L. Lawrence Convention Center in Pittsburgh, PA. Stop by to talk with Senior Account Executive Aurelie Marcotte and Inside Sales Specialist Pedro Benavides about how AROMA can address a range of ambient air monitoring needs, including air toxics analysis, mobile monitoring, broad area surveys, long-term unattended stationary monitoring, and more. Don’t miss Aurelie speaking about Entanglement Technologies monitoring of ethylene oxide (ETO) in ambient air in California and Georgia using the AROMA-ETO on Wednesday, August 24th, at 2:20PM ET in Ballroom A. For the full agenda, please visit the conference site.
Entanglement Technologies’ Aurelie Marcotte and Pedro Benavides were on the ground in the Atlanta area this week using AROMA-ETO to monitor ethylene oxide (EtO) in a minivan outfitted as a mobile lab. AROMA-ETO was co-located at a National Air Toxics Trend Station (NATTS) site managed by the Georgia Environmental Protection Division (GA EPD) during the month of July. On Tuesday, after uninstalling AROMA-ETO from the NATTS site, the instrument was reinstalled in a rental minivan to begin mobile operations. The mobile lab recorded near real-time measurements of EtO in communities, urban background settings, and near commercial sterilization facilities to better understand ambient levels of EtO.
AROMA-ETO collects lab quality data of ethylene oxide in the field below 10 parts-per-trillion detection limits. In addition to ethylene oxide, AROMA-ETO provides analysis for other volatile organic compounds (VOCs), including 1,3-butadiene, acrolein, methanol, and isopropanol.
Contact us to learn more about how AROMA-ETO can convert any vehicle into a mobile air monitoring laboratory in less than an hour. No expertise required.
Dr. Lauryn DeGreeff, an associate professor at the Global Forensic and Justice Center of Florida International University, is currently using AROMA-VOC as part of an analysis of a variety of samples from the 2021 Surfside condominium collapse. A specialist in the analysis of volatile organic compounds (VOCs) by analytical instrumentation and canines, Dr. DeGreeff is undertaking the research with her graduate student, Michelle Karpinsky. They hope to better understand what search-and-rescue dogs and first responders were exposed to after the condominium collapse by analyzing water collected at the site, wipes from the dogs, and other specimens. They are using AROMA-VOC to analyze these samples in order to evaluate the deployment of AROMA for real-time characterization of chemical exposures in the event of an emergency. AROMA has been used to identify chemical leaks after hurricanes and to track emission events from industrial accidents (check out some of our Case Studies here). Reach out to talk more about how AROMA could help with emergency response and other air and water monitoring needs today.
Entanglement Technologies will be co-locating AROMA-ETO at a National Air Toxics Trend Station (NATTS) site managed by the Georgia Environmental Protection Division (GA EPD) during the month of July. Known sources of ethylene oxide (EtO) in ambient air include the sterilization of medical equipment and chemical manufacturing, while other various background sources of EtO are not as well-understood. AROMA-ETO will be continuously monitoring EtO at the NATTS site to better understand ambient levels of EtO in urban background settings. AROMA-ETO provides near real-time, lab quality data for stationary and mobile VOC measurements. It is currently the most sensitive commercial analyzer for measurements of EtO and was shown to have method-detection limits below 10 parts-per-trillion in a recent presentation from EPA Office of Research and Development (Gitipour et al., 2022).

We are excited to announce that we have recently completed building a new AROMA to be used for pilot deployments and short-term projects! We have several exciting deployments in progress and upcoming this summer. Since returning from the Netherlands in May, our AROMA instruments have been used for monitoring projects in Northern and Southern California and Washington D.C. This week, two of our AROMA instruments are traveling across the country again to be used in Georgia and Florida!
Stay tuned for more updates about upcoming field deployments, conferences, and other happenings by signing up to receive our Summer Newsletter.
In addition to adding AROMA to your suite of air monitoring techniques, our technology is also available for short term deployments. Contact us to discuss your monitoring project.
We are exhibiting at the Air and Waste Management Association Annual Conference and Exhibition from June 28th – June 30th at the Hyatt Regency in San Francisco, CA. Stop by to talk with Application Engineer Jake Margolis and Senior Account Executive Aurelie Marcotte about how AROMA can address a range of air and water monitoring needs – air toxics analysis, wastewater surveillance, broad area surveys, and more. Don’t miss CEO Tony Miller speaking about using AROMA for mobile monitoring to map VOCs in communities on the Community Air Monitoring Panel on Wednesday, June 29th, at 3:30PM PT in the Seacliff A Ballroom.
The California Air Resources Board (CARB) is adding AROMA-VOC to their monitoring capabilities for air toxics. AROMA-VOC is a sensitive, real-time volatile organic compound (VOC) analyzer capable of measuring critical air toxics such as benzene, toluene, ethylbenzene, xylene(s) (BTEX) at part-per-trillion concentrations in ambient air. AROMA-VOC can also be outfitted with the additional capability to measure ethylene oxide at less than 10 pptv in ambient air. Learn more about AROMA-VOC.
Over the last two years, Benjamin Bratten, a high school senior at Paul Laurence Dunbar High School, has been working to study sewer pipe leakage and cured-in-place-pipe (CIPP) emissions. He has had a “secret weapon” on his side: AROMA-VOC.
Bratten works with Dr. Kelly Pennell and her lab at the University of Kentucky, where they have access to cutting-edge research tools including AROMA-VOC. “Working with high school students often emphasizes the best parts of research,” Dr. Pennell says. “For example, they authentically embrace the unknown, show up with curiosity, and normalize asking questions about big and little things.”
In Bratten’s study, there are three parts. First, he learned how to use and calibrate the AROMA instrument, working with postdoctoral researcher Dr. Nader Rezaei. “AROMA is easier to use than traditional analytical techniques, such as GC-MS, and it is very accurate,” Dr. Rezaei says.
In the second part of the study, Bratten worked with second-year graduate student Herman Tay to develop a model sewer pipe apparatus with an interchangeable connector to analyze leak rates of various sewer pipe connectors. They then used AROMA-VOC to measure volatile organic compounds (VOCs) that were flushed through the apparatus, including benzene, toluene, ethylbenzene, xylene(s), trichloroethylene, 1,3-butadiene, styrene, isoprene, and 1,2-dichloroethylene.
The third part of Ben’s research, developing a method to measure emissions from CIPPs, is still in progress. As Bratten explains: “CIPP emissions are currently measured by PIDs or GC. I think that AROMA would have a lot of advantages over these techniques in the field.”
Bratten presented his work in a poster at the senior symposium for the Math, Science, and Technology Center at Paul Laurence Dunbar High School (as pictured above). Dr. Pennell shared a picture from the symposium, reflecting: “Ben [Bratten] always seemed excited to hang out in the lab, learn something new, and work together with us to investigate solutions to big problems. We are going to miss him.” Bratten will be attending Texas A&M University in the fall of 2022 and plans to major in chemistry.
Entanglement Technologies is exhibiting at the 2022 Air Sensors International Conference in Pasadena, CA from May 10th – 13th.
Entanglement Technologies is continuously working to meet the critical and changing needs of the air monitoring community. Last year, we released AROMA-ETO, which can detect single digit part-per-trillion concentrations of ethylene oxide in ambient air. Please visit our poster, “AROMA-ETO: Part-Per-Trillion Sensitive, Realtime Ethylene Oxide Measurements in Ambient Air,” to learn more!
