Regulatory compliance in air quality monitoring is essential for industries emitting hazardous air pollutants (HAPs). Compliance requires high-precision measurement solutions that provide real-time, accurate, and cost effective monitoring of volatile organic compounds (VOCs) and air toxics.
Entanglement Technologies’ AROMA, powered by Thermal Desorption Cavity Ring-Down Spectroscopy (TD-CRDS), delivers sensitive, real-time measurements of key air toxics, enabling industries to streamline compliance, reduce costs, and improve operational efficiency across a range of applications. AROMA is also a critical tool for ensuring environmental sustainability and worker protection across industries.
AROMA for Air Toxics Monitoring
Unmatched Sensitivity & Selectivity: Detects critical VOCs such as ethylene oxide (EtO), benzene, and 1,3-butadiene at parts-per-trillion (pptv) detection limits.
Robust & Versatile: Deployable for stationary, mobile, and multipoint monitoring applications.
Alternative Test Method (ATM) Eligibility: AROMA provides real-time, high-sensitivity VOC monitoring that can be submitted for EPA approval as an Alternative Test Method (ATM) by facilities seeking compliant solutions.

Ultra-sensitive VOC detection for pinpointing even the smallest leaks
On-demand, real-time analysis and no need for canister samples or lab delays
Automated concentration mapping to visualize leak locations and trends
Detect leaks before they lead to violations
Regulatory alignment with LDAR (Leak Detection and Repair) programs
Mobile and stationary options
5 Stack & Source Testing
Beyond traditional stack testing, AROMA enables precise VOC measurement for emissions characterization, process optimization, and compliance. Its rapid response and high sensitivity provide unmatched data quality across various industrial sources.
Key Features:
High-sensitivity VOC detection for compliance and process control
Real-time data with minimal downtime and high accuracy
On-site, mobile deployment for flexible source testing applications
Portable and easy to deploy for quick source assessments
Supports regulatory reporting and emissions characterization
Compliance Across Key Markets
Monitoring with Entanglement Technologies’ AROMA analyzer aligns with air quality regulations in the U.S., Europe, Canada, and other major markets.
Examples of key regulations include:
United States
EPA Hazardous Organic NESHAP (HON rule) – Effective April 9, 2024, the updated HON rule mandates stricter emissions standards for facilities handling HAPs, including benzene, 1,3-butadiene, ethylene dichloride, ethylene oxide, and vinyl chloride. Requires fenceline monitoring and root cause analysis at affected chemical plants.
EPA NESHAP for EtO Commercial Sterilizers – Requires continuous emissions monitoring (CEMS) for ethylene oxide at nearly 90 sterilization facilities nationwide.
South Coast AQMD Rule 1405 – Requires CEMS and fenceline monitoring of ethylene oxide emissions from sterilization facilities and related operations.
EPA Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) – Proposed rule aims to reduce sterilization worker exposure to EtO. Facilities must monitor EtO in both processing and non-processing areas and trigger alarms when there is an exceedance.
European Union
Industrial Emissions Directive (IED) & Best Available Techniques (BAT) Conclusions – Establishes stricter VOC emissions monitoring requirements for industrial sites.
Air Quality Standards (2008/50/EC)- Enforces limits on benzene and other toxic air pollutants.
Canada
Canadian Ambient Air Quality Standards (CAAQS)- Sets national air quality objectives for benzene and other hazardous VOCs.
Environmental Emergency Regulations- Requires risk assessments and monitoring for facilities handling toxic substances.
Navigating Global Compliance Challenges
With increasing complexity on air toxics compliance, industries need fast, accurate, and cost-effective solutions. AROMA provides the data and insights necessary to meet evolving compliance needs worldwide while helping facilities reduce cost, minimize environmental impact, and safeguard workers.
